For anyone looking for used equipment, I too have been looking for a place to post some used equipment (and buy some) and came across this new site from sealcoating direct
that allows you to post your stuff for free.
I read some other information about it on another site and it sounds like it will be very big and your membership is free (for now anyway) as long as you sign up soon.
It sounds like it will work like craigs list. The name of the site is Buy My Asphalt.Com
and it's only for the asphalt and sealcoating industry
