I got a 2.5 (they have 5 gallon too) mini bow from petsmart. It comes with a rim that's black, blue, or red. I picked the black one, you can see it if you look at my album. It's great, but you have to be careful with it so you don't scratch it because it's acrylic. It's good though and pretty sturdy. It comes with a filter, water conditioner and lighting. The light bulb needs to be switched out though to a flourescent since indcendescent lightbulbs will cause the tank to be too reflective on the sides and stress your fishie. He'll be okay though. :)
I don't think bulbs cost too much, just make sure it's the right size.
And get silk or live plants, plastic is not good at all, but you might know that already.
