I got my DMT8X from amazon (through a partner site, some fishing supply place) for $43 shipped. If I recall correctly amazon had the DMT8XX at the time for $55ish shipped, it was a sale price too (They retail 90-100ish like you mention). It appears their sale now is $73? So still well below retail, but yes marked up from a month or so ago. Possibly because most of the other sellers Google turns up are out of stock until after Xmas?
