Well, I have done the same experience regarding Techno. A local retailer claimed around $20K which sounds for me that "some one is earning some money here"...
That?s why I have looked at
www.cnc-step.com which seems to be performing pretty good and have spec's which is close to more expensive stuff.
However I'm not 100% convinced since the machine is equipped with a NC software which only gives support in German (only German web page. Program it self - menus etc is in English). Mach3 seems to be struggling with the supplied controller from
www.cnc-step.com so I'm still looking into other options. I have even looked at
www.sh-cnc.com. I'm awaiting a feedback from a industrial customer which has one of these to hear about his experiences. A lot of crap is made down in China, but if this is working good - it might be my solution. I'm not sure if the 4th axis is supported, but for me living in Europe, this is for sure cheaper solution than a K2.
And YES, you could actually make a truckload of other things than just cues
