Loved the Syma S107. What's next?

So I bought a syma s107 off Amazon a couple weeks back when they were on sale. Holy crap, that was the best $20 I ever spent. Now, having been firmly bitten by the micro-heli bug, I'm looking to upgrade. Ideally, I'd like an indoor micro in a similar size to the s107, but with a little more speed to it, and the ability to "strafe" left and right. My understanding is that this implies a 4-channel heli. I've been thinking of getting a Blade MSR. I know it's 4-channel, but can it strafe?

Can. It. Strafe?

Help me out, radioControllit!

EDIT: Looks like the Blade mSR is sold out just about everywhere now. Guess I'll have to wait :-(
