well the moneys really no issue for me. i'd like to get a tank that i can use again though. plus i heard the the substrate kinda sux for that because its the only kind you can useA Biorb will work for what you want, it's just that they are overpriced for what you can actually keep in one.
I have a little all glass tank, it's about a 12" cube. Put a little internal filter in there, small heater and a 15w 'energy saver' flouro bulb in a desk lamp and you are good to go for low light plants.

however looking at them all the pico blows away the competition...im a fan of salt and fresh so this could be great for later on down the road.
there has to be someway to cover this a bit without killing the light
