I just got a 4-pack of used 30 rnd Bulgy 5.45 mags from ORF (for $19.95 with bulgy mag pouch) and they were pretty darn nice. Best deal I've seen. This was a special deal here (there is a post several pages back), only for phone orders that mentioned the site I guess. No idea if they are still offering them. Anyway you can find the contact info on their website,
www.ohiorapidfire.comwww.rpbusa.com has EG bakelites for $6 or so each last time I saw.
I got a 4 pack of the bakes from
www.Northridgeinc.com a couple years ago (for $19.99), they still list them on their page last I checked but I'm not sure if they actually have any. When I got mine they looked brand spankin' new, came with a pouch, cleaning kit, stripper clips, etc... They want like $30 for that set now though...
