...I have been considering getting Peco code 100 turnouts

The code 100 is a good choice Justin. Not only cheaper in the long run, but the difference between code 100 and code 83 is minimal. Once you paint and ballast the track, it's hard to tell the difference. Of course the code 100 Atlas track is not as detailed as Micro-Engineering, but were I that concerned about the look of the track, then I'd be using code 70.

I stayed with code 100 as I had acquired several boxes of Atlas code 100 flex track and quite a few Peco turnouts over the past few years. I would recommend getting the Peco insul-frogs as you'll have a lot less wiring issues and they are very reliable. Also go with what Peco calls their large radius turnouts, although the medium radius turnouts are just great too and look fine.

Peco has made some changes to the design of their turnouts in so far as they no longer have that raised section where the built in spring is located and also I've noticed they no longer have the extra contacts on the point rails. But after using both the "revised" medium and large radius turnouts, I've had no issues with stalling. I especially like the fact that you don't need to use ground throws with the Peco turnouts and love the way they snap when you align them and how well they keep contact.
