Yeah, it would help to know how you are planning to use the coach as well. Full time, weekends, extended trips during the winter. .
Also, what do you consider "older"? For some, this is 3 years, for others, 20.
I'll +1 on older Safaris and throw older Beaver coaches in there as well because they were basically the same company. We went through the process last year and ended up getting a 96 Safari Sahara. We are currently on the road for 6 months traveling through the south.
These coaches were built right at the beginning and most have held up well provided they received the required maintenance. Other than some PM before the trip and rearranging the living room to fit our needs, the only issue I've had is roof leaks, which were easily fixed DIY on the road.
Just be aware that owning an older coach will get VERY expensive unless you can do all or at least most of the work yourself.
