Marine, I'd say that supply of the sub2k is lowers, not that demand is higher. There are tons of hi point carbines out there for sale, not so many subs. I've seen several 995s on my local armslist, but only 1 sub. GB shows about 35 hi-point carbines listed right now, but only about 10 sub 2ks.
I do wish that the mags on my 995 were easier to load and held 20 rather than 10. I do like the gun, as does my brother, his fiance, and our 9/10 year old boys. I'd buy another in a heartbeat if I had the cash.
I haven't shot a sub2k or camp, but I will own one or teh other someday, again, when I have the cash. Right now, they are getting up there in price.
