Guy's Naposim D/Ball are Romanian. And $700 for 800, well since I'm in Europe an so don't use US$ I'm doing a rough conversation. But my guess is I'd pay about $25 per 100 or maybe slightly less.
To your othr question's, you sound completely new to this side of the sport so a good beginner's stack would be a Deca and D/ball cycle, it's an old cycle but you'll grow on it with few side effects. Save the testo's for another cycle. Before going on with your cycle take yourself over to the anabolic discussion board and research exactly what you'll be putting into your body, research, research and more research.
PM me if you need more info, I don't like to advise too much here without knowing stats, goals, training experience etc..
