A good question. They are beatiful. I guess it's thanks to the CNC mod. Jaydee?
I have a Sherline as well. I agree with Jaydee that it's capabilities are limited - primarily due to the time factor. It is slow work.
If I was to buy a another mill it would be a heavier one but I have not seen one in my price range that could match the little Sherlines accurate feel and precision. Of course it is mostly about ones skill level (mine is low or non-existant) but I haven't seen a larger (cheap) mill with a more repeatable, small back-lash or smooth movement of the XY table for example. (Not speaking from a very wide base of experience mind you)
My major gripe is the z-axis. It is not very stable, doesn't allow me better than 0.05mm accuracy, compared with the XY axis where I can maintain better than 0.02mm.
Overall though, I think my opinion of the tool matches Jaydee's. I'd recommend a heavier duty one for the amount of material you need to cut for waterblocks.
It's great for fine work though, and I do like it. A rotary table makes all the difference as well.
