12 Gallon JBJ Nano Cube or 10 Gallon Glass?

Which one should I get, a 12 Gallon JBJ Nano Cube or a 10 gallon glass that I configured myself? I have hear that the Nano cubes are cheap and fall apart, glass breaking or cracking, and the filters are refuse. I figured it would be about $60 total cheaper to get a cup. I need your advice. I may just win a 20 gallon long but I will decide between these 2 first. Also, if it helps I don't want corals or anything, in recent times some live rock and a clownfish or two.
Answers:    i've never heard anything abd about nano cube..
i hold a 29 gallon biocube and think they are kinda shitty but the JBJ's should be a-ok


if you just needed some rock and a clownfish (a pair won't fit in a 10 gallon) the opt for the regular tank.. it'd be cheaper

whether you did want some corals at one point though i would get the nano cube, ebtter light and filter and natural add-on for a skimmer



EDIT:
i would still go with the 20 gallon (especially whether it comes with a good light)
more space, more dilution, better water, more fish, comfortable to maintain.. the list goes on
Make your own or a short time ago buy a standard 20 gallon. It might be even cheaper to just buy one rather than make one. Nano cubes are expensive!
