I have used them in the distant past.
Just swung the willkdar his way and I see that his ebay shop
(which I used) has been out of action for a few months (bar one recent motorhome related purchase, not sale) - the seller is listed as "away". While the telephone numbers are the same, the address appears to be different - I wonder is the gadge moving/on sabbatical/dead?
FWIW - I had no problems with them. However, you do and under the circumstances, I'd be going the PayPal route ASAP. He's not trading.
