tt81 is ok... 200 300 ish good condition. I just bought 2 for my friends
TT-81 is cheap, but reference class TT-101 is always broken and always listed as junk with no return. Repair of tt-101 cost nearly $2k and can tale a year in the USA (if you’re not in USA like myself it’s terrible). Not everyone is a skilled tech and very few have a tech who can handle TT-101.
Denon DP-80 is better than cheap TT-81 (in my opinion) and always reasonably priced on ebay where buyer is protected and return is possible.
But import tax is different from country to country and it’s very high in Europe if you don’t know (can be 20-30% from the amount that must include shipping cost too).
This is why a brand new Technics SP-10R DD with warranty is better.
I think Luxman PD-444 is great because the owner don’t have to think about plinth (and it’s for 2 tonearms).
