Dollar for dollar, If I was a BL dealer I'd rather sell 4 Thermal Wave IIs, or if you want to count the trucks too, I'll take two TW II, betcha the commission is more, and the sale is easier with a greater chance of a slam dunk on the first attempt at financing.
I learned that lesson on the Titanium wand, most expensive wand, but carried the lowest margin of them all and in the beginning more were returned than actually sold = PITA for a dealer.
