There aren't that many shops IME where you can buy equipment for less than wholesale prices!
I wouldn't get too caught up with the differences between balanced/non-balanced (especially in the 2nd stage). Go for something cheap and cheerful and one that can be serviced easily. I honestly doubt that your dives will require the ferrari-type regs just yet. Later when you get more in to a certain kind of diving, a reg upgrade is pretty common and one reg can be used for pool/CW sessions and the other for the deeper OW diving.
After all that, a balanced 1st stage is very good. I don't think you'll notice the difference in balancing the 2nd.
if you will end up working in the industry and can get manufacturers keyperson deals for less than wholesale.
