I definitely debated getting the AR250 because of the weight and price difference ($20,000 US less than the 252SE), but ended up getting the 252 because of the additional features that I would have otherwise wanted to install (Throttle sync, speed control, speakers, Solid Bimini top) or really wanted, Ie, the back seating area with the sliding seats....Not sure if you would be able to get those from Yamaha to install yourself.
I feel like looking back now, for the extra $10,000 US, the 255XE would probably be a better option because of the SVHOs, integrated wakebooster, integrated ballast, wakeboard holders, mirrior...etc.
