Hi Julie,I have two,one for a year and a half the other for three years with no issues other than as darkblade stated the needle valve is not easy to get right but with a little patience it can be done.I did change out the needle valve for an ideal and have had no issues.

Commercial regulators such as the Milwaukee are fine for beginners, but you may have to adjust/fiddle around with the needle valve a bit more to get a stable flow.

Evilbay regulator: $75 shipped. You can pay $25 to $300+, but for $75, there's no reason you can't have a really nice-looking, perfectly functional industrial (high) quality used regulator.
In order, from regulator to solenoid to needle valve to tubing:

Clippard 1/4 to 1/8 bushing (4CQN) $1.32
Swagelok 2" Hex Long Nipple (B-2-HLN-2.00) $5.03
Swagelok 1/8" street elbow (B-2-SE) $10.15
Clippard Mouse solenoid (ET-2-24) $28.56
Clippard Mouse mount (15490-5, 1/8" NPT ports) $7.29
Clippard Spade connectors (3831-1) $3.71
Evilbay 24V adapter $5
Swagelok 1/8" male elbow (B-2-ME) $8.82
Fabco-Air needle valve (NV-55-18) $34.75
Swagelok 1/8" NPT to 1/8" Barb (B-2-HC-1-2) $4.51

Clippard shipping: ~$24
Swagelok shipping: ~$10-20 (not sure)
Fabco-Air shipping: ~$12

Total: $240.14 (max)
Clippard fittings are very reasonable, but shipping is honestly offensive from Clippard.com. It'll be a bit difficult to source everything without going through the Clippard website, though.
Swagelok fittings are expensive, and you might save a bit on Evilbay, either for Swagelok or any other manufacturer's fittings (they'll all work fine). Shipping is reasonable but not cheap.
Fabco-Air nv shipping is on the steep end of reasonable, but you probably can't get it anywhere else.

The Clippard Mouse solenoid is good quality, and fairly cheap.
The Swagelok fittings can be substituted with any other manufacturer's fittings.
The Fabco-Air valve is decent quality, *definitely* better than anything from a prebuilt rig.

You can save some cash, maybe up to $50, by substituting Swagelok and Clippard fittings by Evilbay fittings.

On top of the listed price, you'll need at least one check valve, tubing, some type of bubble counter, and drop checker (recommended). Add another $20-30 for those.
This is really helpful, thank you. So it seems like the regulator isn't that expensive, but all the fittings and components add up to at least $300 if you're getting SS or mostly SS (including a tank and all).

Yes, that is a reasonable starter setup.

For CO2 the difficulty in purchasing a full regulator setup relies in the intake and outake tubing size. CO2 art, a site sponsor, appears to have some nice setups: Planted Aquarium CO2 Systems Specialists | CO2Art.co.uk

Form personal experience, I've found that if you look into CO2 regulators for beer production you might be able to find one that handles the right tubing - there are a multitude on Amazon.

True. The trade-off, however, is quality. With one of those cheap prebuilt units, you get a fragile, unreliable regulator, a solenoid of dubious quality, and an imprecise, touchy needle valve. Which is not to say that there aren't units that perform adequately for years. But many people upgrade from those intro units within a year or two due to frustrations with performance. Consider those units (Milwaukee, Azoo, Aquatek, Dici, etc.) an introduction to pressurized CO2.

kevmo911 Oh, and a 5lb+ cylinder @ $65+, plus fill ($10-20). So The total, including extras and filled cylinder, comes to $355 max.

There are various commercial regulator setups that are available, as well as various companies that sell custom built regulators. Finally, there are also users on these forums that sell setups from time to time (check the For Sale subforum)
