any one have info on these scales
are they accurate?

I have had one since they first came out. I also use several other scales including digitals, and the 304 is always spot on. Also about the easiest to use. I would never be without mine. Go for it! Russ

whats a good price for a used 1

I paid $200 for mine in '82, if I remember correctly, and it still works perfectly.
