You can find them cheaper. I got my 14bff for $200, and you can find D44's for $250 and up. 4.10 is a good ratio, but $800 is a little steap unless they are in really good shape. Also a D44 isn't a 1 ton front end, its the 3/4 ton. A D60 is the 1 ton. They usually start at $1000 each though. A D44 axle can handle alot of good wheeling, and can be made to handle tires up to about 38". You should already have a D44 in the front of your truck, and you can convert that to the 8 lug bolt pattern to match a 14bff alot cheaper then buying a new one. I am currently converting my 1/2 ton front end to 8 lug, and it will only cost me around $200-250 with all new wheel bearings and all parts needed for the swap. So you might consider just buying the 14bff and converting to 8 lug until you can get the money for a D60, or if you don't plan on running tires over 35-36" not switch at all.
