   Yes indeed, they're getting very attractive. I'd want one capable of handling the standard rack panel width of 19", and probably 14" (8U) high, for homebrew stuff, so it would probably get well above $300, but still, compared to what things like that cost ten or twenty years ago, or the cost of a full sized CNC standup milling machine, it's dirt cheap.

A cnc mill / router is cheap now.  I bought a kit and built it, use it to make pc boards, labels, etc.

Think it was 300 dollars shipped, took a weekend to build.  Love it, also put a laser in it when I want to etch stainless, etc.

  The fun part was making nice compound radius cuts on the corners of the panel, to fit the enclosure. My milling machine isn't CNC. I've got a rotary table for the mill, which would make very nice circular radius cuts, but not compound. So it's the old fashioned way: trace out lines on the panel; make rough initial cuts, and then remove tiny bits at a time on the bench sander, check the fit; another touch on the sander; check the fit; another touch on the sander...
  One day I'm going to get myself a CNC router, robust enough to cut at least 1/8" or even 3/8" aluminum.

There is no neutral wire in Europe.

  It's just green Rustoleum, but it matches the paint I used on a couple of other DC bench supplies that I restored, and the case has just about exactly the same dimensions as those, so it'll look fine sitting beside them.

Nice job.  Like the color, too.

This is incorrect.

There isn't split phase feed in Europe.   It is 3 phase.  There is still a neutral conductor.

This doesn't mean anything in regards to the OP, however.  And his question is answered and solved.

   Yes, I hope they're more proactive about getting the word out next year. And Tom, if you're interested in that sort of thing, the Steam Up event is October 5th this year.

Just seeing this now…sadly, I’m only 15 minutes away and had no idea it was on.  They used to send announcements by email and postcard. 
Hope to hear before the next one.

   In addition to ham gear, I love building my own test equipment for the bench. Here's one I just finished today: an adjustable 0-1200 VDC bench power supply. The project was actually inspired by my acquiring nice empty cabinet at the last Nearfest. What to build into it? I've got a nice old Heathkit high voltage bench supply, but it only goes up to 400v, and quickly runs out of gumption above 100ma. So, empty cabinet, plenty of transformers, chokes, caps, and meters handy; it's going to be a power supply!
  Nothing complicated: a Hammond 1250v transformer, Triad swinging choke, bridge rectifier, a variac, a couple of old panel meters, and a can of green spray paint. The output connector is an SHV type.
  The mismatched panel meters wasn't intended. Always verify the functionality of old panel meters before cutting the hole in the panel, not after! (Ask me how I know this.) I was lucky to dig up another meter that fit the same hole/screw pattern.
  Also note, in the pictures of the uncovered chassis, how close the filter cap bank comes to the rear of the panel meter. The cap is actually touching the meter! Angels watch over fools and builders who don't measure before drilling holes!
