Well, giving us more info. about the model of TT you're buying, what the feedback rating of the seller is, & the distance it's being shipped would help us in giving advice. Are you buying some high end $5K TT? Or a used Rega P3 for a few hundred $$? If something along the lines of the latter, I wouldn't worry too much. But communicate your concerns to the seller in advance--make sure they have the original packaging, & that you feel comfortable with them. If you're buying something for a few hundred $$ I wouldn't sweat it too much. If you are, just go to your local dealer & pay the new $$ price & get a warranty, etc. Buying used always entails some anxiety--do you want to save money, or have total assurance? Good luck!
