Need Selling advice

If you're uncertain, I would list them all together and encourage offers for parts. I frankly think you will get more $ if sold separately. The question you need to decide is if $ is more important than ease. If ease is most important, do as Thorman suggests - all together, local sale only. If $ is most important, you're likely to get more for it if you will ship it. It's not hard to package a turntable securely for shipment, but in my experience few know how. If you're not certain you can package it for cross country ship - then local sale is a must.

I agree with Thorman, package and pick up only. There is no other way to safely sell a turntable. Each one I have purchased from A'gon's was done that way. E-bay is okay, but again must be a package deal, pick up with cash only.

I agree with Thorman - Try to sell it as a package with local pick up, especially since you have no feedback here. If you get offers on the individual pieces - Then decide if that works for you.

If you are shipping, the dustcover, arm and cartridge will have to be removed anyway. Each will need boxed up for protection. Many times the platter on the table will need removed as well.
Have you tried headphones?

FINAL NOTE: Ebay really sucks these days. They no longer cater to the little guy, only big businesses. GO AUDIOGON!
