That VMC looks ok for the money, could be good or could be a can of worms. If it was closer i would defiantly be having a look. I wouldn't go near the Japax WEDM. WEDM is cool but you need deep pockets to keep them running. The two sinker EDM's look good, they would be the ideal size for a backyard machine shop. Really good for removing broken taps and drills, plus you can do other cool stuff with them.
