Advice on buying an used Panasonic VCR
 

So I'm thinking about buying an second VCR and as far as I know Panasonic is the best. I will use it for playing tapes and I'm looking for longevity and durability. I'm from Europe so I'm talking exclusively about PAL players.

There are many offers available for the Panasonic NV-HD630. There are single offers for the Panasonic NV-SD45 and NV-HS830.

I don't know much about VCRs to be honest, so I'm looking for any tips. Which of these are the most appropiate for playing tapes? Any other suggestions?

Thanks in advance.
