What's the best drop-in for SF C2, Z2?

What's the best thing going right now, that I can drop in my Surefire C2. Looking for combination of runtime, power, and high quality. It needs to be something that's readily available.

Thanks,
Dave

From best so far, it seems the Bugoutgear Q5, the Malkoff M60 and the Deree Q5. As for a cheaper one from DX, the 1447 http://www.dealextreme.com/details.dx/sku.1447

The Malkoff is not always in stock. Bugout and Deree is best option, I ordered a Deree Q5 dropin with smooth and OP reflectors for 33 shipped today for my Z2.

Also keep in mind the cheaper DX ones seem to be good, but sometimes they die or short out on people. I spent a little more just to have a reliable light. I wanted to get the 1447 linked above to test side by side with Deree Q5.
