Lookin at Bearcats for sale, & I'm thinkin I should have at least one of them. What are the differences between the Bearcat, & Super Bearcats I've seen advertised ?? Is there any reason I should try to find an older example, or are the newer ones as good or better than the older ones ? It's not really an "I need One" situation, it's more of an "I want one" urge.
