Technics 1200's are built like tanks. If you're using it to just listen to music and not to DJ, one that is brand new could possibly outlive you. I owned a pair for dj'ing for almost 10 years. During that time they probably got used about 4-10 hours a week, and I never had to repair one. It's the only brand I would trust buying used, and you could probably find one in good shape for a reasonable price.
Whatever you decide on, try to get one that has a standard removable cartridge needle and an adjustable weighted tone arm. That way you can get a good quality needle and it can be balanced properly. As mentioned earlier, if you're willing to spend the extra money, get a direct drive table rather than a belt drive. I sold my tech's last year and have been using a plain jane player for the time being. I think I want to get one of Gramma's players. They look sexy as hell.
Shure makes really good needles as does Ortofon. Buy a brand new needle and make sure it's balanced properly to make your vinyl last longer. I can help you with that if I happen to be in town.
I should point out that the Debut III's are belt drives. Honestly though I feel like that accounts for part of the sexy.
I think I found the pairs you are talking about.. What's up with that thing in the middle? I'm sure it has something to do with DJ'ing, but is it attached? And the one pair doesn't even look like it has arms.
I'm taking a look at a used Tech 12 tomorrow. Owner claims it was bought new in 09, asking quite a reasonable price, so going with cash in hand hoping it's as claimed. If that pans out, it's time to go shopping for the rest of the kit.
