Easiest Canon to mod?

[R26 oldtimer]

I've been thinking of getting a used dslr of MPB to modify. Most likely candidates are 450d-500d-550d, although I could get a cheaper 350d and use my unmodified 600d to focus via live view, then swap cameras at the t-ring to fine tune focusing via short subs.

So which one of the Canons is the easiest to self mod using Lifepixel tutorials?

I bought a 600D off MPB - Advertised "Like New" it arrived in a condition I would describe as Good. They must have missed all of the scratches and the gouge mark on the LCD. I managed to get a full refund but just give the camera a good go over when you receive it as it must have been a Friday afternoon when they quality controlled the camera I was after. They did resole the problem I am just not sure it should of occurred in the first place!
