Many responders to Gon threads will be basically 2nd user enthusiasts, having come at the thread site through the for sale section. I am no exception and my whole system is 2nd user and ex dem. Responders have pointed out the problems with used turntables, well all items you might buy have problems. Top of the list is Cartridges of course, where any prior use makes a purchase questionable. That did'nt stop me buying a Koetsu Rosewood Signature and being thrilled with the purchase and saving(about 1/3 of the cost of a new unit in the UK). We are, or should be realistic about the risks of buying 2nd hand, but have calculated the saving is worth the risk.
Turntables should be a relatively safe bet, but being mechanical, I would agree the risk is in transport. It's easier in the UK, but I have always collected mine. To add my experience, I would not go for a Linn, which I used for years. IMHO, an old design off the current pace. There is an upgrade path, Cirkus, Lingo, trampoline etc, but it's expensive. To get the best out of them, they do need rebalancing periodically. even if not disturbed.
I would agree with many of the suggestions of tables to consider, but some other UK ones are not highlighted. Avid is a great company, with fine sounding, well engineered, fit and forget tables, again with a potential upgrade path. My own final choice is Origin Live, a Resolution with Illustrious arm. I know you can get better, but at what price. In the UK at least they are hard to beat value wise. I am aware the current Dollar rate makes UK/European kit very expensive in the US, so Origin Live is less of a bargain. For Classical gear, remember the rim drive Garrard 301 and 401, if they are available in the US, if replinthed they make an unbeatable sound, with the best base you may hear from vinyl.
