The Personal Defense Network, which we've posted here before (including earlier today) has a new premium annual membership option. You'll find that it's substantially less expensive than many single training DVDs and much less than some other monthly-membership video training sites.
Full disclosure: I'm friends with Rob (the guy narrating the video) and I believe he and his staff to be excellent instructors. I will never, however, be able to dress as well as he does off the firing line (nor as well as Brian Montgomery for that matter). I lack the gene, I guess. Don't let that stop you from reading or watching PDN.
