Heres the deal, and why its just spamming if you put it on ebay and then post it here.
1st off, if its on ebay, then its really not available for sale anyway. If I put a mic on this forum, you can claim it and have it in the mail tomorrow, at the price I had listed.
If I want to claw and fight with other people over a piece of gear for a week, I'll go hunting for it on ebay and hope I get what I want. If it pops up in the forums, it should have a set price or best offer and be available immediatly without going though the ebay trouble.
If its on ebay and thats what I'm looking for, I'll go to ebay and look for it.
Personally, I never ever post anything on ebay without posting it here first and giving everyone about a week to grab it up if they want it. I always kinda considered this place a bit of a brotherhood, and therefore I offer my goods, and quite often buy my goods, to or from someone here 1st at a fair price, and not in a race to see who can win something at the highest possible price. Sorry if you don't feel similarly about your peers. Ebay items do not belong here, they belong on ebay. If you are looking for highest price, then this is not your place. Hard to argue that.
Put it here 1st, ebay second, or ebay 1st and leave it. Thats my opinion.
