I have a 3x2x2 tank right now with no problems with heat. I use a Mercury Vapor Bulb (T-Rex Active) on the warm side, which provides both heat and UV rays. On the cooler side I have a energy saving bulb for light and I don't need anything for heat. If you go with a strip light (ReptiSun 10.0), you will need an additional heat source, which is why I prefer the MVB. I don't have a screen-- I use clamps to position the bulbs.

I monitored my temps with a probe on each side, and now I use a temp gun.

Not that hard to clean. I wipe up poop asap, vaccum it out every few weeks, and wipe down the sides when they look really smudged.

I don't have problems getting Bebe out, BUT I'm 6' tall and our tank is only 18 inches off the ground. When we upgrade, I'll get the 4x2x2 tank with sliding doors. $200 here- http://www.glasscages.com/?sAction=ViewCat&lCatID=6 Shipping is high, but its not bad if you can meet them at a show or pick-up.
