$2,000 isn't much in digital, barely gets there in film for something medium format.
A contax body in LN condition is $1,700, plus you need a viewfinder, film backs and lenses, which will push the price way beyond your original 2 grand.
If I had 2 grand and wanted something for life I'd buy an M-8 and shop around or some 24mm lens. That will still push you to about $2,500, but if you don't get caught up in the "need" more syndrome you'll have a very good but quirky little camera that should last a long, long time and it shoots a dng file which will process in anything and it's ccd which has a different look.
My m8 is strange, but it's very tough and I'd never sell it.
IMO
