Hi Maccy
I guess you have read the info on this site regarding the Millenium programmers. As Rolfw said on a previous post, the 'Elvis' does take a lot of beating and I've never had a problem with any card when using it. Since Ad-teknik have written Multiprog8 for it, programming funcards is easy. Also, Multiprog by TJ is an excellent variation of the software for the Elvis as well. I don't know too much about the Millenium 3 but I use the Elvis because I like to take the easiest and least problematical route for doing anything. No doubt other contributors will have been successful with alternative methods.
best of luck
Jimbo
