I looked up the license number and it comes up as Roberto Miranda and just because he's a tech doesn't mean he doesn't have enough money to buy the stuff in the first place. There's any number of reasons he might be selling his gear not the least of which is he's jut tired of it. Look him up and send a snail mail to check if it's for real or not..
I'm looking up his name on Facebook and checking with 3 people of that name on the theory that it can't hurt to make sure.
