Many good points have been brought up. Since this aspect hasn't been mentioned, I will chime in...
There is a world of difference in a Norwood Hydraulic mill and an LT40HD. Yes, the Norwood can have hydraulic capability, but when you look at one in person, IMO it is not very robust. Hydraulics take a beating and when you look at just the physical size of the cylinders and the components they operate, the durability just isn't there. It may be OK for Pine and smaller diameter hardwoods (like they have in Canada), but you start handling 24"+ oak logs from the Appalachian Mtn's, the life expectancy is going to be much shorter. The backstops are weak and the chain turner leaves ALOT to be desired both in function and the materials it's built out of.
If you were to compare strictly on price alone, an LT35 would be right inline with the price of the Norwood w/ hydraulics. The WM is built MUCH heavier and the durability is far greater. You also have the option of a debarker too. The blade guides are far better, more accurate tensioning system along with many other little things that can add up quick. But those little things can make a big difference in your long term investment. The downside is the WM can be a more complex machine to work on, depending on what/how may options it has. Down the road, a basic LT40HD walk along with no setworks is going to have fewer headaches than an LT40HD remote with all the bells and whistles.
The best advice I can give is find a fully hydraulic Norwood and LT40 and observe them both operate. It will also give you a good chance to look at the meat-n-taters of how they function and what they're are built out of. Then you'll be able to see with your own eyes what I'm trying to pass along. Looking at a mill without hydraulics would be like shopping for a 1 ton 4x4 truck but end up test driving a 1/2 ton 2wd and trying to take it off-road...
The other option would be to go to a show. Then you could observe them operate side by side. I'd bet money you'd come home with the WM.
Hope this helps and best of luck with your decision.
