I'm looking to buy or build a diamond drag bit holder for my CNC mill and am looking for plans to build one, or suggestions on where to purchase the holder and bits. This is for a hobby machine and the cost needs to be low! I have found a few on the web but they wanted way too much for them. Are there some low cost options out there? I can't believe they get $200 plus for one. They seem quite simple to make. Am I missing something?

Thanks for the help!

greolt and others made some on this forum (http://www.woodworkforums.com/f170/anyone-doing-diamond-drag-engraving-88889/).
One of them link to a kit on Ebay for $89 (http://cgi.ebay.com/DIAMOND-ENGRAVING-KIT-cutter-Master-ROLAND-OMEGA-PCUT_W0QQitemZ190173940529QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116) that includes the holder and bit.
