There is some really good Minolta lenses out there but they are raising in price and is getting rare
I can recommend to buy the A-100 with a used 50mm and 70-210/4 make sure it's the f/4 (beercan) it's one of the cheapest lenses I currently have but probably the best. The 50mm could easyly cost more than a brand new Canon but the 70-210 is really cheap compared to what you get, about 160-200$. I would guess that the two lenses will cost you around 300$ if you can find them... I have a review of the 50mm lens here. The higher noise of the A100 is because of a weaker anti-aliasing filter which should make the image sharper but with more noise.
