I am going to side with VirginiaIron on this question.. I am the proud owner of a 1952 Ford 8N (and previously a 1950 Ford 8N that I gave to my Father) and could not be happier. The older tractors are so much easier to work on yourself without the reliance of a dealership. Heck, the Old Man and I even sold our John Deere 2210 SCUT with a front end loader because we enjoyed the ease of maintenance on the Ford 8N so much; there isn't a thing you can't do yourself with these old machines maintenance wise. Everything is easily accessible when working on them. Not to mention these tractors pack plenty of power for gasoline engines.
On the other hand, when there was a leaky front axel seal on the John Deere 2210, we had to take it to the dealer so they could remove the entire front end to simply replace a small seal in the front axel.
These reliable tractors can often be purchased in the ball park of $2500-$3000 for a sound working machine along with several attachments, which is even a bigger bonus. If you're not shy to running a gear shift, vintage and reliable tractor, I would take a look at some of the old Ford, Massey Ferguson, Farmall, and International tractors.
Ah the memories of Grandpa farming two hundred acres and putting six kids through school with that 8n. Some of it with me sitting on the fender. Wish I had one.
