Buying used Procharger?

Here is the deal...less than 1000 miles on a P1SC. Comes with 42lb injectors, 8 lb pulley. seller calims all i need is a Cobra fuel pump. Even comes with 2 core intercooler, and a Diablo chip.

Is it worth 1500? Am i opening a bad of worms by buying something used? I know the seller. He blew his motor with this supercharger, by not "having enough fuel" with the Stock pump. What are some dangers....BVTW, I will have this professionally installed..
 
If you don't buy it let me know. I will buy it in a split second, broken or not. Also you can't really tell if its good unless you send it out to be pressure tested and or put it on. Dude, for 1500 buy the blower.
