I've been riding for 50+ years and I was never able to convince myself to drop that kind of cash on riding gear. Until last year when I found a like-new used RC suit for $400 on ADVR. Looked like it had been hanging in the closet it's whole life, i.e., never been farted in! I have to say that I'm still on the fence about 'needing' it. It's great for trips and touring when you're in it the entire day. Pretty comfortable and surprisingly flexible with respect to temperature extremes--not unbearably hot into the 80s and pretty warm into the 40s (altho you start to need extra inner layers below that). On the flip side, I never wear it for my day rides of 4-5 hours just because it's not as convenient as a two-piece system for the stop-n-go type of riding. Plus now that I'm old, fat and crotchety, it's more of struggle to get in and out easily....I usually look like I'm trying to escape from a kidnapping attempt as I try to wiggle out of the thing. As for fit, if you're buying new, the sizing chart will give you a pretty good idea of where to start and I'd recommend calling and talking with the staff about any custom styling you want done. Buying used, you're on your own, but if I remember you mentioning you're 6'3"ish and over 200#, make sure that you get the torso length long enough and the chest size right or you'll be uncomfortable.
