Hi I have two TLRs from Rollei an old one from the beginning 50. is and a GX f2.8. Booth are good cameras the old one has no lightmeter in it. But needs also no batteries!
I payed for my 1991 GX which was used from an amateur 2-3x a year 1800 USD. But I have it from here in Switzerland and I think you get it even cheaper from germany! My cheap old one has a self timer, its nice for some family shoots so all can be on the pic, it is with the Tessar f3.5!
If you have time you will find a much cheaper one in my opinion!

Cheers Armin
