RE: Discontinued model
No even the "sells well" runs are terminated for newer models.
I have a nice Funtana S90 that went out of production in favor of the 100X, which also went out of production for the new Funtana 1.25.
My Funtana S90 still looks pristine in spite of a couple of crashes, due to my learning how to repair it...
Good selling models are no guarantee, neither are the name brands, who you buy it from, etc.
Your best bet is to learn how to fix your own planes, or deal with airframes as one big replacement "part".
