yeah good luck trying to find a decent ACTUAL 64 pattern bag. I had one issued to me and it was junk.
personally I've had it in both configurations. I've always prefered having it set up in a jump style (well I kinda have to now being in a para coy

)
dropzone tatical has made some pretty slick stuff on their site, pricey yes, but the stuff on there will last you forever. it's a nice kidney belt that they sell on there, extremely comfortable.
the place I went to for the longest time was in manitoba. the frames were $50 a pop. he doesn't have anymore though.
though I've heard of stores in oakville that have them still new in the bag for like $60.
I'm doing an order right now for frames for my unit, so if you want to tag on, I'll see what I can do for you.
