I have various tanks, two nano's and a 100g. The nano's were the expensive tanks as they are reefs and I have put an excess of 3k total in to both of them. But then I wanted a big tank and was no longer 'rich' so I did it on the cheap. Dont get me wrong people know me, and my apartment smells of leather bound books and rich mahogany, but I got my 100g up and running for $250, total. then I went and spent another 60 or so bucks on fish and currently have 5 fish, 80 - 90lbs of LR, sump, overflow, powerheads, lighting, heater and some other extras. I can safely say that I will never buy anything thats not a deal again. So dont be discouraged in tank price, the deals are out there.
