Pros: Very reliable!
Cons: Not real attractive.
I have a 1994 Classic. It works great. I can't think of a single problem I have had in the 10 years. I did have a problem with the Tip Top cover though. Unfortunately the liner broke up after all these years. So I needed to replace the whole cover. I really liked the Tip Top. But the conventional cover works well too. I would buy another Hot Spring if I ever upgraded. But I think this spa will last me for quite some time yet.
