"I don't understand people's aversion to buying vintage turntables."
+1. Many of the vintage TTs offer superior performance to new models, especially at the <$500 price point the OP has specified.
I have had great results from carefully selected Thorens, Luxman, and Empire vintage turntables as well as vintage MM/Electret cartridges.
The biggest problem is getting them shipped safely as many sellers don't have the original packaging nor the knowledge to correctly disassemble the table/arm and pack it properly to avoid damage during shipping.
The other key to success is knowing how to setup the table for proper functioning. Manufacturers' instructions for packaging, setup, and operation are available for most models from vinylengine.com.
