Need Advice on TE Problem

My TE fightstick has been partially broken since last year. If I recall the RT first stopped working, then the LB went, and just yesterday the A button stopped too. I called MadCatz about this and they said they would send me a new PCB and now a year later… I called again about a month ago, and they were still out of stock??? Just called now and yet again.

So what should I do: send it in to MadCatz (though they still don’t have it), keep waiting, or buy some PCB by myself and try to fix it (I’ve never modded any fightstick before, though I’ve been told it’s easy)?

P.S. … or demand gold fighstick as compensation?
