If money is not a problem then sell what you don't use and get what you want. Bare in mind once you sell what you have it will be hard to find the quality products that you get rid of. You know what condition the cameras and lenses you currently have and you probably cannot find items in as good condition as current items. Good luck with your choice.
I currently have Nikon F100w/85mm1.8, Canon EOS 1N-HS, Mamiya645E, Pentax K1000, and a bunch of lenses for each. I won't part with any of them and I use all my film stuff. Digital is all Canon 20D 40D, 5D. Looking for a rangefinder myself!!LOL (Like I need another camera!!!)
