to be honest it seems, that post counts dont really work to prove your honest, ebay defiantly does in my opinion and also poeple kbnowing you in the real paintball world past the forums but as some people nowadays can get 300 posts in a month and a half etc, post counts have gone out the window.i just brought a marker off a guy with no posts but he got a friend with 500+ post to vouch for him.. a sent the friend a pm and was happy with the response and and brought the marker with no problems.
if you have an ebay rating and 200 is a good rating ... put that in your post when selling......
a lot of people have ebay accounts and probably could vouch for you if you sent an ebay email from one member to another ...they may not know you personally but can vouch you are an ebay member with an excellent record
