No Worries on this. Matt has hooked me up with a lot of good stuff over the last couple of years for reasonable prices too!
The quick run down is that he is based in Florida USA. Friendly guy who knows his transformer stuff and won't rip you off with falsely advertising things and excessive postage charges. You can pay paypal too which is great. He only ships stuff out once a week though and his packaging is adequate but not bullet proof. Hope this answers your questions??
