Agreed... getting a good and "useable" cassette deck really depends on the demand and performance you expect.. particularly with vintage models. I have repaired several different decks, models from Akai to Technics. They all demand a different part or method to repairing the drive mechanism, usually multiple belts involved. After repair however most operate well.. given most are abandoned just for the broken belts to begin with

.
On another note, there are basic

models, usually piano key models, that work well because of their simplicity. Then there are the advanced models that followed, functions such as Auto Reverse, Double Auto Reverse, adjustable tracking, superior noise reductions, etc... that merit a lot more know-how and care to fix.
It sounds as if the OP is just looking for something "simple"

and this can be had in a basic deck, easy to find on EBAY or the like for small dollars investment.
After cycling through many a deck that both disappointed and surprised in performance. I use an Onkyo for taping, auto-rev, with B/C NR, it works great! I then use a very basic Kenwood, no frills, single direction for tape play and reviewing.. basically it checks the Onkyo's recordings.
So.. performance depends on the demand.. you need not stress over "quality" and such if it does.. what is does
