Re: [CAD_CAM_EDM_DRO] Firsthand Defiance experience

Dear Marcus,
Thanks for your kind advice, that's I
wanted to know the real feed back from user rather
than sales people's colorful wording. You are right
that may be the reason they got out of business. Only
I was impressed with that machine by reading an
article published on MMS online
http://www.mmsonline.com/articles/109804.html

Thanks once again, I should continue my search with
something else pl. let me know if you got any
recommendation. BTW I found this site very interesting
http://www.desktopcnc.com/mill_table.htm
may be of any use for you. Thanks.


Cheers,
Kevin
