Be warned: A lot of the used Ebay PMD's last less than 60 days.

 

An eBay PMD should be used as a "tester" or a "git back" spare.

Once you confirm the PMD is the issue, you should pony up some dough for a good one like those sold by heath diesel or PMDcable.com.

Unless you don't mind taking your chances or dealing with more frequent breakdowns.....
