I have a Norwood LM2000, as do several others here, and its a good machine. I can't say how it compares to a TK as I've never seen one. Being from Pa, you could drive up to Buffalo an pick up a Norwood and save yourself the shipping $$.
The LM2000 is an all manual mill, but then again, so is the CSM. If you purchase new, you will need to assemble it or have it assembled, but if you do it you WILL know all about the mill prior to using it.
I opted for the trailer package and 23hp among other things.
I was cutting some 6 month air dried walnut last week, and cut boards up to 22" wide. Its definitely quicker and easier than a CSM, and makes a much narrower cut. Fuel consumption and noise is minimal compare to a CSM.
Norwood has a forum on their site.
