I am glad to see some sense talked about regarding TB10s. I hear too many people slating them when they haven't even flown one!
As for the parts, they are not as scarce and expensive as many would have you believe. If you compare the cost and availability with Piper and Cessna then yes, they are not as plentiful or cheap due to the mass production and alternative makes of parts for these more popular makes.
Given a stonking crosswind i'd take a TB10 over any Cessna or Piper i've flown any day. The 25kt limit is well deserved in my limited experience.
