It matters how you look at it really....you're going to run into basically the same issues with either one (venting obviously one)...are you going to be dissatisfied you got the smaller one after you worked all the kinks out? You may want to plan your whole set up, and look at the total cost as a whole....I'd ask myself 'is a few ounces of primo bud you grew yourself worth that thirty dollars you saved in the beginning'?

I guess I'm a bigger is better type! lol....
