Ok here's my 2 cents. Get the china Kat.
Why? I have followed several threads on the 4200xl and I must say most are happy with it, but almost all upgrade the pump, valve block, drive motors and etc. there are many who has not changed a thing and its still kicking.
For a lesser price you can get the china Kat and you will find that you will change the same stuff as the more expensive 4200xl. The parts you remove from the china cat can be resold as long as there not broken, it will supplement the cost of upgrades.
The major differences that I've gathered is with the 4200xl you'll be having fun for some time before you brake something or just want better stuff in your machine.
eventually you will change the same stuff in the china Kat anyway.
But if you want to do less mechanical work 4200xl is your machine.
