I think in making so many models and so many options available to the consumer, the price of the Deeres are driven up as well (after all, if you make all your tractors the same, you should be able to do it cheaper, right). At least in my area, Deeres are ridiculously expensive, but we only have one Deere dealer in the western end of the state (although a couple more have started making inroads) that has three locations. When shopping for a 40-50 HP tractor, the quotes I received from the Deere dealers were $6,000-$10,000 above the other tractors (NH/Kubota/Kiot/Mahindra) that I was pricing. I would guess though that pricing is greatly regionalized and that Deere must be very competitive with other brands and (as CowboyDoc says) offer something for everybody. In our area, the professional full-time farmers use some John Deeres, but there are a lot more older IH tractors than anything else, along with new Massey Fergusons. The newest tractors that our heavy-hitting farmers have been using are the Cat Challengers (and hey, JD offers competition for that too). There are also alot of the 70s and 80s Fords/NH running around - not really a dominant brand here, but there are not too many dealers (1 Deere, 2 NH, 1 Kubota, 1 MF and then the "off-brands").
Anyway, back to topic: If you need a true compact tractor for under $5,000 and can live without Hydro and power steering, ROPS and live PTO, I would say go grey market Yanmar. If the grey market scares you and you can live with a slightly larger frame tractor (like a Ford 2000, MF 135, etc), go old American Iron, although many of these may not have power steering, hydro, or ROPS, depending on model. If you want new and want to take a (small) chance, go Chinese.
Good Luck
