Well my first deal for a used SP01 fell through. Its funny buying items from ads online. Some people are just odd. The seller would not even reply to my messages most likely because he was upset I was asking for less than he wanted. On the contrary the current seller happily met up with me and thanked me for my offer and following up by showing up. Offered the same price for both adds.
Anyway, I was able to grab a SP01 for $400 with 300 rounds through it. The P-120s go for about $350 new so I figure I did pretty well.
Here is a pic. I wanted to follow up since I made the post to let you all know what happened.
