are you looking at a 8780 or a 8780xp, there is a big differance between them. the 8780xp has more hp and a constant speed rotor. you might be able to upgrade the 8780 to 8780xp specs. i think you will be happy with either machine. we ran the small mf 8560 for 10 years with out any problems. have now traded up to a mf 8570. good luck with whatever you choose. neil
