IMO, LHS support stops when they do not carry what you want. By all means if he wants one of the two setups his LHS has then supporting them is a good option (if they are a good LHS). If he wants a different setup that they do not sell, there is no "bad karma" with ordering off the Internet. Only purpose of my post was to let the OP know there are setups that cost a lot less than the Tekin or Castle setup, no matter where they are purchased.
