just wanted to see what everyone think about it. here is the link
Digital Ultrasonic paint coating thickness gauge,meter - eBay (item 230292866280 end time Sep-28-08 20:39:43 PDT)

if that doesnt work here is the item #230292866280

 

I would rather buy one off the forum sponsors

 

Great price if it works good. Not worth much if it doesn't. I would do some google seaches and try to find get some more info on and reviews on it.

 

FYI, the seller is in Hong-Kong:duh:

Got this one from Phil and super happy with it.

 

It is not an ultrasonix thickness gauge but it is an electro magnetic instrument.
This product has only one problem, that it is too large and two hand use. The externeal cable if you are use too much will broken near to probe or connector.
Much better the interneal probe version forexample this! http://herbil.hu/elmatronicfn.jpg
