I have three MKII's, a MKIII, and a new MKIV. I got my first MKII over 30 years ago and have never found any of them overly difficult to field strip, although I admit the MKIV is a piece of cake.
Although I didn't find the MKIII difficult to field strip, I did add a Majestic Speed Strip kit to it which made it downright simple. I would not hesitate to recommend a MKIII if you don't have one.
