Only if you realy want one. The ones worth money are the units 100% complete and original with all docs and software. I have a LC 550 (same unit just not black) and to be honest it is no big deal. TV tuners are pretty much useless these days in the US with the switch to digital TV.

Personally I see all kinds of rare gear being listed at crazy prices with few people buying, they do this to make you think its worth money and then they can sell a few at half price or something.
