10 - 29/30 gallons, is there much of a price difference

[lil.guppy]

I currently have a 10 gallon tank. No stand, no equipment yet.
My question is, if I have to buy a stand and all the equipment am I better off just getting a 29 or 30 gallon or is that going to make my price go way up? Is there much of a money difference in a 10 gallon versus the larger ones?

Well size of furniture can go up the larger it is if that is what you mean. Start up costs for tanks are more for larger tanks, but the difference wouldn't be THAT much. Live rock will probably be your largest expense (besides inhabitants that is).
