Exactly. Street is $449-$459; crossgrade street is $259-$279 so an add-on with your DP purchase/upgrade/crossgrade for $225 would have worked for me. I would think that MOTU would see more $ at that than they saw from my reseller.I like that. Buy DP at full price get M5 for 1/2 price.
Put it in the same box to save on shipping and include a serial number so we wouldn't have to mail the card in for support (ok, I haven't needed support for MachFive but still, if they already know whom it's going to...).
