I'll probably try a couple of those.
What about a tank? I was only looking at the fluval 12g because it was an all in one and it was rather cheap. I didn't like the height though. If I do get one I would prefer rimless, and around 10 gal.
I may build my own. I was thinking 24 x 10 x 14.
If you're confident building it, it's definitely the way to go; that or get one built for you custom. Probably cheaper than you'd expect, depending on who does it; but the obvious benefit is getting something to exactly fit your needs.
For dwarf puffers, you could get a simple braceless tank on the cheap, then add a small hob and the clip on lights; sounds shoddy but I find it looks and works well
