I'll cast my vote for the John Deere 5003 series as well as the 500 series Massey Ferguson's. there's a good selection of tractors from all makes in this class though, so take the time and do your homework, drive all of them you can, kick the tires, ask questions, etc.
I can't speak for other makes of tractors in this class but I can speak on the John Deere 5003 series as I bought a brand new 5203(56 engine hp and 47 pto hp) with MFWD a few months ago. in 2007-2008 these models were upgraded with features such as MFWD, single rear remote, syncshuttle and syncreverser transmission(depending if you bought 2wd or 4wd), and all have turbo. I paid $19,500 for mine and also got 0% for 48months, awesome price for my trade-in ($1,000 less then the price of the tractor the day it was bought new in 1978). when all added up i just couldn't say no to the deal even though i wasn't planning o buying a tractor at the time. anyways, I was hesitant about the whole made in India thing but from research i learned that alot of people are being misslead. these tractors are made in India, BUT it's not like they're being contracted out by some other manufacturer, John Deere themselves are building these machines in a brand new plant in India. go look at one up close, you will see the quality in them. so rule the India thing out. they also come with a Dana front axle in the MFWD models and a Cararro axle in the 2wd version.
As for the Massey Ferguson, well the ONLY thing that made me not go with them was one simple reason. no dealer closer then 45 min to my farm. the JD is 15 min away. that was the only issue i could not get over. had there been a MF dealer closer, i would have bought a MF 543 or a 563. i was sold on them from the moment i sat on one and drove it around. VERY comfortable tractors!
