New Old Camera

So I've been thinking about buying an old film camera. I've recently become fascinating with this Minolta Maxxum 7000. The interesting thing about this camera from the mid 80s is that it was the first ever camera to have autofocus built in. I've been searching all over eBay and local pawn shops to try to find one and the best part is the price. It's only around $15-$20 for the body on eBay and they still work. I'm trying to figure out which lens I want to buy with it. I'm looking into maybe a Minolta 50mm f1.7 AF, but I'm not quite sure just yet. Any ideas or suggestions would be much appreciated.
