Of course there is always the case of having just a bad machine whatever make it is. I was down at Alltec last week and a guy I know from the Fast Track days was there. He is considering a Blueline 'T' Wave as he is paying too much tax, and want to offset some. His dilemma is that he has an old Steamway 910 like yours, only his has only given and continues to give good service even with close to 6,000 hours on the clock.
I have run TM for over 6 years now, my first a Steamway Sidekick, I have never had a solution hose go on me, even though I frequently abuse them.
Well maintained TMs, well looked after and serviced when due shouldnt give undue problems unless something is seriously wrong with it in the first place.
