[Shop-talk] Source for used equipment?

[Scott Hall]

It's time for a new sandblaster and parts washer.  Before I trundle off 
to Harbor Freight, I thought I'd ask if anyone knows of a good source 
for used, much-better-than-H.F.-quality equipment like that.  I've 
checked eBay and Craigslist and so forth with no luck.  I'd prefer to 
buy it once for more, but used is a lot more palatable.  Any ideas?

Thanks.

Scott
