I know nothing about the company, but it does say free global shipping on orders greater than £20. Is it safe to go with a single stage regulator?

Youíre going to find dissenting views on this subject. If you are diligent with your setup and are sure to check your CO2 once a week or so, itís my opinion that there is minimal risk with a single stage regulator. The standing pressure in the tank will start to drop once the tank runs out of liquid CO2. If that pressure drops too far, the regulator can suddenly fail and, in effect, open all the way. You typically have at least a couple of weeks between the time that the standing tank pressure begins to drop and the ďend of tank dumpĒ. If you fill your cylinder before you run out of CO2, it should be a non-issue. Even with a dual stage regulator, you really donít want your tank to run out because then youíre going to be delivering inconsistent CO2 to your plants.

Oh now I remember it was co2art.co.uk. I had seen this setup. Read that it is sold my the same manufacturer in China.

I'm not sure if they are the same or not, but I was looking around that website and I'm pretty sure I saw the same ones on a China site as well. Makes me wonder about the true origin of some of the more expensive ones on Amazon. I'm sure many of them are still made in China, so I can't imagine that an expensive one from Amazon or a cheap one purchased directly off a site and shipped from China, really has any difference?

Am I allowed to post the direct link to the regulators I was looking at on the other site?

And so is replacing a whole tank of dead fish or plants smothered by algae.

I seriously recommend saving up for a quality system. CO2 malfunctions cause some of the most heartbreaking disasters this hobby has to offer...

Unfortunately I'm just here looking for cheaper suggestions.

If you get this one, make sure you go with the upgraded needle valve; itís worth it. Youíll also need an adapter if you want to use paintball canisters. With this combo, the only other things you will need are; a bubble counter, brass check valves (the normal plastic ones will harder from the CO2 and stop working), and a means to diffuse the CO2.

Iím using a canister filter, and found that the inline CO2 diffusor from UpAqua has been great. Itís worth buying an extra ceramic piece, that way you can swap it out each time you clean the filter. You can then clean the dirty one without having too much down time on your filtration.
This is a really interesting unit. Looks like it was produced just for our hobby. Since we are such a small niche in the market, manufacturers haven't or are slow to catered to our needs.
It is extremely compact. Might be a benefit if you're trying to hide it under a stand but it certainly is much less modular then a standard set up. The input pressure gauge reads up to 3500PSI which is a waste since CO2 tanks are less then 1500 when full but this is fairly standard and not a huge deal. The output pressure gauge leaves quite a bit to be desired. It reads up to 140psi and no one comes close to this pressure. (If you're going to make something just for the hobby, tailor the product to the hobby) Would be difficult to use with low pressure systems. It is also a single stage regulator so that is an issue. It is made for vertical output tanks... maybe these are common elsewhere in the world. It also doesn't say whether it is a CGA-320 nut, it only uses the term standard. Maybe standard is British or maybe it works for paintball.

Even their dual stage that claims to be built for the hobby has similar issues. Plus the solenoid doesn't come with a US electrical option.

Don't get caught with your plants down

I completely agree with the issues about the pressure being higher than our typical needs. However, they also offer a horizontal output option, they mention it's compatible with CGA-320, as well as the optional paintball adapter, and the plug needs to be selected from a drop down box (UK vs US).

I can't comment on reliability other than it's worked great for me. Anecdotal evidence is anecdotal, but I can say that I've been very happy.
