Any feedback on Len Dawson parts, please???

Just wondering whether anyone has dealt with Len Dawson (sells NOS parts). He advertises in the Plymouth Bulliten (and has done for years) and he has the parts that I want. BUT, he doesn't have a secure page for payments by credit card on his website and he is asking me to give my credit card details to him through a HOTMAIL email address???? Anyone had any dealings with him that way?
Appreciate some feedback before I buy.
Many thanks
Gary
