can see you have posted on the 'for sale' section to a guy selling a creed....
now i dont know the guy but if I was buying,
I would look at how long the guy has been on the forum..... and the guy selling the creed has been on since 2004, so thats a good start
I would look at his post count and may be look at what his posted or sold previously.... has he get good feedback? was everyone happy last time he sold something?
and then if I was still unsure may be ask the guy selling, can any other members vouch for him... the paintball world is close knit community and everyone who is a good guy can usually get three four people to vouch for them.
EDIT Just Noticed LUMP vouched for the guy, thats as good a vouch as you need
I would be more than happy dealing with that guy.
hope that helps
