Parts for our T4.

[sugarplumsss]

What experience have you garnered regarding:

T4 has a problem, and the availability of parts for it!!

Related:  I saw a used T4 , but it was around $2300!  But in better shape than mine.. Of course I play live, and this particular one looked sheltered.

Seemed tempting to have it for a whole new set of parts.

parts may or may not be the death of a keyboard,
1. you can do without a certain function, given the large number of buttons/ functions. Analogy, you can do without a spare tire, or an electric window, or AC!

2 how likely is a critical part failure apt to be the end of usefulness for the board?

3 Is there only a very small number of unavailable  and vital* ( *motherboard ) parts, that given some good luck. this keyboard can last another 10 years?
