There is no doubt that coach has Flexsteel - they may be putting something in an ad to avoid this fact, I haven't reviewed anything you may have provided link wise, just reading the thread.
Buying now is a hard NO for me. People are still trying to capitalize on where they could have been 3 months ago. Ain't gonna happen. NO one should be buying now in my opinion, not even NEW. Wait for the end of the year and revisit the opportunities. While time is no guarantee, we have to live our lives now, otherwise I would be cancelling my upcoming trip I really don't want to go on for fuel prices, but we must move forward so for those that feel the need to do it now, I support you, go for it. If you can wait, wait, we are in a decline as you all know, great deals are ahead. I've bought great things in economic declines, wait for the buyers market, we're still in the remnants of a sellers market, at least sellers want to believe that and will try.
As to the tax situation, in some places they can be delivered across a border to avoid a sales tax by the dealer, you'd then pay the tax in your state on registration. Always remember you was the buyer makes the decisions, not the seller. If they want it sold they'll go the extra mile to capture the sale.
