RE: mSR vs. mCPX
I had considered a mcpx too but after I thought about it a little I got to thinking it would be a little too confining inside just learning collective pitch and pretty light for outside just learnig. I go along with the 450 philosophy too and ordered a belt drive clone the other day. Theres so many options to choose from with the 450's and they can be bought for unbelievable low prices on some of the sites. I like the Blade stuff but the best thing they have going for them is you can get parts for them at just about any LHS and bind-fly is nice with theDX6i. I wish they had the clone parts as well but you have to order everything online but most of the time it doesn't take but a few days.
