Are these prices you received to have someone install the central vacuum or just for the unit itself? I installed my VacuFlo myself, I have a split level colonial and it was fairly easy. I have 4 inlets, one inlet per floor does the trick for me, and I have no issues with using a 30 or 35 foot hose. I wouldn't consider myself very handy around the house, I can learn to do something and execute it well, but I don't have that knack of just knowing how to do things. I am meticulous about details and I watched how to videos online and on YouTube before installing my system, I read all sorts of directions, and I talked with my vac shop about how to properly install the system. Overall I spent about $1200 total on the unit, piping, inlets, and power nozzle and hose kit. The VacuFlo 566Q unit I purchased at a discount but it was still around $800. If you can install the system yourself it really shouldn't cost you an arm and a leg, and with only two inlets it shouldn't be difficult. My only regret is that I didn't put an inlet in the garage, you may want to do that if you like to vacuum your car yourself.
My other go to machines are an Electrolux Epic 6000, similar to your 6500, and a Kirby Diamond Edition. I love them both but the central vacuum handles the majority of my cleaning and does it with such ease. It really one of the best purchases I've ever made.
