I use the one I had for keeping plant cuttings in by a window. So if I ever need that extra java moss/hornwort/bit of java fern for anything--there it is.
I don't think that the hex tank is terrible, but the incandescent light definitely isn't very good, and the tank doesn't provide a lot of horizontal swimming space. If I wanted to use it again, it would probably be for a temporary purpose and I would keep the light and the filter off. That's me, though.
I really prefer the Marineland Eclipse tanks, now that I've gotten a few. I love the design of them, they are a bit pricy compared to similar kits, but I have found them to be good quality, and if you get them online they're not so bad. If you get them used, or any acrylic tank used, you should take into account that acrylic can get terribly scratched if you don't take care of it, so make sure you inspect the tank before you buy.
If you ever think of upgrading to better heaters, I recommend these: http://www.fosterandsmithaquatics.co...8&pcatid=11368
they're only a little more expensive than the minis, but they offer great temperature control.
