Great! Try to get his references' numbers. That is how you'll know for sure. Also his address, try to google earth it or type it in google and see what comes up. If its a hotel, no go :).
Oh and some more information on Mr. John Abell.
If you type it in its a contruction company. I know that there are many John abell's in the world, but scammers usually pick names like that. Also, try to put two and two together, if he is from China(I know in this case he isnt), his name better be Chinese...or at least a knockoff American name that sounds like Thomas Choo or something. An American/English first and last name for someone in China is a sign for caution.
I would email those people and see what they say. I would post up the replies and see if the people have the same style of wording.
Its hard to see if he is legitamite or not. I almost got scammed by a guy called Benny who was selling face plates. He was selling them at 8cents US and would only sell in bundles of 100 each design. I asked for refrences and samples and he said he would let me do 1 order with MO of 100 total. He would only accept wire transfer tho. I was almost going to do it but i had an odd feeling and left it. He emailed me once after that when i said i couldnt afford to do the deal he wanted. Now his website seem to have dissapeared!
SIR TO MY KNOWLEDGE ANY NOKIA 8800 AT $145 IS A FAKE, NOKIA REALLY CONTROLLED THEIR PRICE, AND NOKIA NEVER HAVE INTERNATIONAL WARRANTY, THE WARRANTY IS ONLY VALID AT THE COUNTY WHERE IT IS DISTRIBUTE ONLY, YOU CAN WRITE TO NOKIA.COM TO VERIFIED THIS, THANK YOU
Just be very careful when someone only accepts wiretransfer or western union.
let us know how you get on
