Our family has owned MF since the dawn of time it would seem. Having said that, I looked at every brand before buying a 471 recently, and this site has been most helpful. I can't tell you my experience with the 471 yet, but I will mention why I went with it...
1st. I bought a 471,
4wd, 8X8 shuttle,
FEL w/ HD bucket and HD pallet forks.
2nd. No other major brand came within 2k of the price. the JD's were at least 4k more, and the other MF quote I had was 3k more...
3rd. The lesser known (and in my estimation, most likely to NOT succeed) brands were all cheaper, but by very slim margins (1-2K).
4th. I have used Perkins engines for many years, and had no trouble.
so, in my case, it was quite a simple decision.
