I've been flying the 45 for Flex for over two years and have over 1000 hours in it. It is a good airplane, but does have some limitations (as all airplanes do). The reliability has improved and I rarely have a squawk that grounds the airplane. I just flew 5 days (25 hours) with out a single squawk. The article in AIN is pretty good, and if you are buying new I'd get an XL. Get the APU, don't get the freon A/C that Flex planes have. The A/C works great, but after 3 years they still don't have a fix for the aux. heater that is part of that system. The APU provides good heating and cooling and you won't have to have a GPU. It's a versitile airplane that is very easy to fly. The wing is very good at altitude and crusies at .80 ISA +5 and colder the majority of the time. I would reccomend the airplane if it fits your mission proflile. PM me if you have any specific questions.
