I have the unfortunate pleasure of owning a 2004 SL10. It has about 2500 power on hours and about 1000 cut hours. the 300 volt powersupply has taken a crap. This has been by far the worst machine tool experience I have EVER had. EVER.
In the past year I have spent over $8000 in repairs. That is just in the last year. I am beyond disgusted with Haas.
I have no idea what it's going to cost to get running again. But it's out of here after it's fixed. I'll never own one again.
My first question would be, did you buy it new? If not, good luck. After seeing the condition most of the "good used" equipment is in, I wouldn't buy someone's junk unless I knew who it was I was buying it from and saw how they took care of it. Most of the time, a company won't get rid of a machine unless there is something wrong with it in the first place.
As for the power on hours, that seems kind of low for a 3 year old machine. My Mini Mill is a year old and has lots more hours than that.
