Nakamichi deck service

Need your advice on where to better service my 682ZX deck.There is nothing wrong with it, but I am afraid that with Nakamichi being out of business it is soon going to be difficult to get original parts.I am thinking about two places:ESLabs(highest reputation,specialize in Nak only and want only $200.00 authorization up front)and Sound Smith(I would not have to deal with the shipping,possibly cheaper,but they service many brands and want $650.00 authorization).So, what is your opinion? Did anyone compare them? I heard that Sound Smith do Tandbergs quite well, but that does not necessarily mean Naks as well.I value this deck a lot.Thank you in advance.
