If the table you're buying uses an AC synchronous motor, I don't think one for use with a 60Hz power line will play at the proper speed with a 50Hz line.
I have no experience with the current crop of budget tables, but the U-Turn Orbit seems to be getting a lot of good notices but it definitely uses an AC synchronous motor. I think you're going to need to look for something designed to run with 50Hz power.
