Well honestly given the cost it's your best move. Yes some of the Konica stuff was plasticky and yes, more people seem to have left batteries in them over the years but the TC is a decent solid camera body....I used one for years until I upgraded to a Nikon FE and beyond and I missed it the whole time....so now I have three more, all good and cumulatively still less than a comparable Nikon!
I would think about a TCX, runs on AAA batteries, Dx for film speed with manual override and very bright viewfinder. Cheap enough to by 2, one for a backup.
