I was just looking at those skates at Source for Sports as well. The CCM Ribcor Platinums (a 68k with 70k tongue and steel). I was pleasantly surprised to see they have a $50 promotion running right now, so they are only $349.
Right now I have a pair of CCM Super Tacks. They fit great, but I think they are just too stiff for me. I thought I'd give the Ribcors a try and see how they feel.
