I've never tried those from Midwest Research, but I best one's I've used have been those by the Dreamspring Institute (www.subliminalcds.com). Very effective and backed up with a lot of information plus they offer a full one year guarantee on all of their subliminal CDs.
That's one of the reasons I bought from them.
On a side note, the subliminals by Eldon Taylor are good as well though I haven't used them since I was in High School (14yrs ago). However I remember them as being effective.
Sincerely,
James
