We run 4 of these machines. They are loud, big and ugly, That being said we still run 2 we got in the mid 80’s ( Nike Dual) 1 about 5-7 years old (Stealth Fighter) and 1 about a year old (Stealth Fighter).
Never a problem getting parts or questions answered. They are made to last a long time. There is not much down time with them however we do winter maintenance and strip the van down pull the units out replace the carpet inspect EVERYTHING, if it wears it goes. Not a big deal to have a van off line in the winter but to do the same thing in the summer would kill.
All in All we like them they are quirky but who isn’t? We had a
chemspec 860 ran it for 600 hours and traded it in for the newest one it just wasn’t holding up well.
