I'd be very surprised if a bike with cantilever brakes couldn't handle 32mm tyres. Why else would it have them?
It's your money - but you really don't know enough to spend $4000 without wasting most of it. The wrong bike can make your life - literally - very painful. Buy a popular model of cross bike, used, off ebay, get to know what your tastes are and the how your body reacts to different riding positions, then buy a bike that's right for you. So many people who do what you're doing end up offering someone an amazing deal on ebay.
