New setup for computer store

Is anyone using this program for a computer store setup? how are you getting along with it and what problems will i incounter?
anywhere to get a headstart?

I´m selling computers, parts and also give support to companies and i´m going well with my quickbooks pro 2001, i think all depend on the size of the store, at least my company is a small one and the QBP fill my needs, i recomend you go for it
