Eric, I've got a 248 I bought new in 2000. I've got almost 1000 hours on it and I've done nothing to it other than scheduled maintenance. I've used the machine beyond it's recommended capabilities numerous times without harming it.
When I shopped for my machine, I didn't shop price, I can't even tell you how a Cat compares in price to other brands. I demoed a number of different brands that are available locally, and I found the Cat to be the most user friendly. The hydraulics are very powerful for its class, in fact Erskine, a division of Bobcat at the time, told me they were the most powerful in high flow when I bought my blower.
Another factor that entered in to my decision is I live 10 minutes away from H.O.Penn, a full service Cat dealer. If something does happen and I need parts, if not in stock they will be brought in overnight in most cases. I don't know if the other brands offer this or not.
