Not sure what to buy

Been looking at getting a new planting rig. Already bought a CaseIH 1250 12 row and now deciding what tractor to put on it. Currently have a 7120 MFD but not sure if it has the hydraulic capacity i need. Been thinking about a CAT track tractor that I can set up with autosteer and do all my field work. A little light tillage, planting, and grain cart. Spotted a few CAT 45's in the 6000 hour range in Nebraska where I farm. I know its plenty big for what I need. I only farm about 700 acres so the price tag looks really attractive for what it apprears that you get. I've heard a lot of great things about these tractors but also some horror stories. I'm looking for something to set up and keep for a long time. Would it be a bad decision? I don't know how the service from Butler Ag is going. I guess that's a big concern of mine. I've read some forums about these but I get more and more confused the more I read. Thoughts?
