I am in the market for a clean 269 but the A model seems to be the only one in my price range that is in nice shape.  Most have the 1145 blades with hydraulic dampeners.  I have heard both pros and cons.  Hear blades come out of phase easily??  I need some help!!

There are a couple of things to look at on the 269. The first is, when were the dampers broken down, cleaned, and adjusted last? If they are maintained they work very well for a long time. Second,If the friction is adjusted during buildup until all three dampers break at the same load, the machine will fly sweet.
Elastromerics are nice, but not really needed.

was once bold, now just old

No the hydraulic dampers are not bad... like said above... The problem with any 269A out there that is still flying 1145 blades... I don't believe the records on those blades anymore... they haven't made 1145's since 1977 and with only an 1366 hour life you really think that many are still going with 300-500 hours remaining like everyone always says? Somebody has pencil whipped the logs to stretch a few more hours and sell the ship... maybe not the last guy but the guy before... Get a ship with 1190's... you can still use the hydraulic dampers or if you want to spend the cash you can get elasto's.... Beware the 1145!!! ask any blade shop... the 1145 was a fragile blade and has some real hassle ad's if you really maintain them... sure your blade doesn't have cracks yet but how many hours are really on that blade?
