It's been awhile since this thread started but I felt the need to post a reply.

It really doesn't matter which brand you buy (excluding the Chinese stuff). Most are comparable.

What isn't comparable is the service you get after purchase. If you have some knucklehead service tech taking care of your equipment your cost of ownership will be high. If you have a conscientious tech, who cares about the quality of his/her work, then your cost of ownership will be average or lower than average.

My recommendation would be do more research on the selling dealer than the brand and you come out a winner every time.
