You have options
Dont let this drop; if you sent hard earned cash and this guy didnt complete his end of the deal-you have recourse.
You have a home address for him-file a claim with the attorney general in his state. You sent payment out of state-notify the local authorities in his state. File a police report.
He has $1100 of yours. Chase this guy. If he is going to keep it then impart some misery on him and let him earn it.
Also, if you pm me seprately I can tell you how to do a look-up on his phone numbers so that you can verify addresses.
Also-you might want to pm VinceF through this board-he is on top of how to pursue a situation like this.
Dont drop this-you owe it to yourself and others who might go through this guy.
If you have this guys profile on RJ message him and let him know the deal made it to a public forum.
Later,
Scorp
