Leslie,
I like the idea of the moble stuff but was always a little unclear as to how this all would work. There are lots of hang us up anti-kickback laws, so how does having someone come by with their moble unit work for us in offices such as ours. Are you adding some "value Added" service or what?
Purchasing is possibly a good thing in most markets but here values don't move that much and one still needs enough money in the bank to afford the down payment, closing costs and the like to be able to afford the purchase in the first place. Ya know, those damn rich doctors! lol
