I went throught the various threads and have concluded that Chris's version of "Cuddles" is pretty spot on, He did a fair bit of research so it's pretty accurate. I will just use the Tasca M4A3 for my donor kit.
I also intend to build a Strathcona M4A3E8, just not sure which one yet.
I have built a couple of the Tasca kits and they are really nice, not perfect or a beginners kit but very nice to build. Having said that Dragons M4A3E8 that I converted to a BCR M4A2E8 was a beauty, certainly one of thier very best kits, and the price point is pretty good too.
I think I'm fairly set to take on "Cuddles" but need a bit more info on the M4A3E8 and then I'm good to go.
I will try and take pics of the builds, my photography has really sucked in the past but I have better equipment now, I will try and post something.
