That's what I have now, but it's got weak flow and probably is too small to hold enough biomedia to keep the tank going in the long run. I'm guessing a canister would be my best choice, but they really are expensive. Are there cheaper models anywhere? And I guess HOBs aren't completely out of the picture. Any suggestions?
Aquaclear HOB was my go-to filter for years... it fit the budget and its got generous space for various media, really, you can stuff whatever you want in there.
If you do want to go canister you could try the TOM Rapids Mini Canister. Its not the best canister filter EVAR or anything like that- and it can be annoying to service- but its a good little workhorse and would be more than enough for a ten gallon. I'm running one right now on my 30 gal monster tank just to have an extra volume of bio-media... it does solid work.
I vote for the aquaclear with a solid blue or black background on the tank to hide the filter body. No matter what you're going to have SOMETHING in the water showing. No matter what you're using, an intake will be visible.
