Fairlight-CMI

The lightpen on my IIx seems to be working fine but I got to thinking,
if it DID go bad, would that basically be the end of my Fairlight? I
mean, I know you can use it to some extent without the pen, but that
would kinda suck.

I was just wondering if anyone knew anything about getting these
things serviced. I hate to think that my multi-thousand dollar
investment is hanging by a little coiled cable. :-( I know Peter Wielk
is supposed to be the guy to go to for service, but I'm not sure he
could do much in the way of lightpen repair. 

So...anyone else had any experience with repairing lightpens? CRTs as
well, for that matter.

Just having a moment of panic here. :-)
