$5k for all that? I'd be on it in a heartbeat... and I've already got a mill! I have the Norwood HD36, but worked around some LM2000 mills. Very simple, rugged machines. Main things to look for on a mill that has been sitting is dry rot on the belts, make sure cables move freely, lube anything with a grease zerk, make sure guide rollers turn freely, put in fresh gas, change the oil, and put on a sharp blade. Set tension and tracking and start making sawdust.
Norwood has a couple of sharpeners. I've got their Pro, which uses a wheel grinder and have sharpened other blades on it. It takes a few grindings to get the profile to match the cam, but no problems. I did modify mine to grind anything from 4 to 7 degrees, but pretty much just use 10, even on hardwoods. Setting is pretty important, too. It is amazing how much variation in set there is, even in new blades. I'd suggest you set the sharpener aside for now and use a resharp service, until you are experienced with the mill itself. There are a lot of variables, and at this point you shouldn't have to wonder whether a wavy cut or other problem is caused by the mill or the blade.
There are a lot of LM2000 mills out there, and Norwood does a great job supporting them. They will not sell you parts, however, unless you register with them and provide the mill's serial #. Their web site has a great forum that you might want to check out.
By the way, Norwood will be at the Paul Bunyan show in Cambridge, OH the first weekend of Oct. That would be a great time to meet with them. They send their top people to that show. Then there's the Sawmill Shoot-Out at the show, too.
