The Q-Up is a remanufacturing of a Thorens product from the 70's. It seems to work fine if you have room between the tonearm mounting position and the platter, though it can apparently look scary to see the tonearm go flying up. Never tried one as I have a AT Safety Raiser and Expressimo Lifter around here in a parts box. I think they are around $60 and you can buy from the manufacturer or from a dealer. On the Q-Up website there are mounting minimum distances and even a template you can print out and see if it will work before you order.
