Last winter, my 19 SRX had zero warranty claims. This year, (second season) I've had about $1000 of work done under warranty. If I'd bought a cat this would have all been out of pocket. Warranty on these sleds pays itself.
The only thing that made the cat more appetizing imo, was their better belt life. Now that the Ultimax xs 825 belt has been discovered this point is moot. My record on an 8jp belt was 104 miles. I've got 1400 miles so far on the Ultimax with lots and lots of long pulls. I can attest, that Ultimax belt is one tough SOB!!
