Yikes - a hundred bucks

And your still thinking about it

Seriously, if it hasn't been knocked about then $100is a a very low price. The link I gave describes the tone arm as 'universal' so possibly not the strongest part of the combo. I haven't downloaded the manual from Vinyl Engine but that will very likely give some extra info about it. Worth doing as the arm / cartridge compatability can be crucial.
Lots of recommendations in other threads here in the Vinyl Circle. A very popular in the last 18 months or so was the Audio Technica 440MLa but it has got expensive (used to be around $80 - Needle Doctor is now asking $199).
It should be possible to buy a reasonable cartridge to get going for under $100.
Do you need to budget for a phono stage or does your present amp have a phono input?
Where is every one around here?
Wayner, TCG, anyone?
