Since JPJ decided to be crass and talk about money, you will learn very quickly buying a coach is not cheap, and buying a Liberty is even more expensive. I know a couple of things that I hope others will comment on.
First, it is probable the Liberty will hold its value as good as any other converter's product and better than most.
But more importantly, long after you have forgotten how much you paid you will still be secure in the knowledge you have one of the best, if not the best coach, and the level of support that other converters provide will rarely equal the continuing support Liberty will provide. It is hard to place a pricetag on that support, but when you need it it is priceless.
