Interweave Knits is the best one out there, IMO. Its quarterly, but has tons of projects in each issue, and some really nice ones at that. If you're going to subscribe to anything, I say with with IK
Interweave is definitely at the top of my list. Creative Knitting is good, too. Then there's Knit.1 and Knitscene geared to the younger crowd.
Is there a way you can get ahold of an issue of each mag you're considering? You can get an idea of what types of projects they have and if you like any of them.
