Switches for someone with limited finger strength/dexterity?

Hey guys,

My Razer blackwidow with cherry blues broke and I was looking for a replacement. I haven't really had a chance to try the different switches but I was hoping someone with a bit of expertise could help me out. Although I've gone to computer stores and "tested'' different switches, it's difficult to actually determine what switch would be better if used for several hours.

Specifically, if there is a better switch for someone with limited dexterity and strength. I had no problems with my Blackwidow, and I think the Cherry Blues were nice and didn't require much force.

I was looking at the CM Masterkey L, and was deciding between brown or blue switches. I'm in Canada and was hoping to spend under $200 or so if that helps.

Any input appreciated!
