kk, here is my suggestion. Give each town its own marketplace. You can only set up shop there. That way if we want to go shopping we can, if we don't we stay away from the vendors.
As far as teleports, that is only gonna work if level limits are set for each town, otherwise it is going to cause more problems in the long run.
As far as setting up a shop just to show stats, you can trade them and show them the stats but never actually complete the trade.
The selling things in KQs was taken out because people were getting the key in Gold Hill and refusing to open the gate unless someone bought it. So, we had to give up some of the good to get rid of the bad.

One thing to remember is no matter what you do, you will never be able to make everyone happy. Someone will complain no matter what.
