You have NO film cameras and you want to buy one?
I see little sense in buying a Film Camera which does not fit your DSLR kit – so you already have a Pentax DSLR?
I also see little sense in shooting 135 format film and then scanning it – if you already have a DSLR.
Buy a 6cm x 7 cm; 6cm x 9cm – and scan - maybe,
Buy a 5” x 4” or 10” x 8” with movements, sure, I see the potential and the advantages.
***
If you want to play with film: then develop it and print it from neg, yourself, which in most situations means exclusively B&W.
OR
Use transparency – and really test your skill sets.

What do I do with film?
I still have my full kit of 135 Format (Minolta) and also my full kit of 645 Format (Mamiya).
I sold my 6x7 format (Pentax) kit really early after cutting over to digital.
Recently, I sold my 5x4 (Linhoff) as I hardly used it, but I loved it and thus I kept it for too long.
I shoot only B&W and hand print from neg.
I loan my 135 Minolta gear to Students.
I got a Canon SLR body recently (really cheap). It fits all my Canon Lenses I have bought for my DSLRs and I use that Film body mostly always now, even though I love my Rokkor Prime Lenses . . .
and I still love my Minolta Kit . . .
