Which Matte Box Will Work?

[JT_Productions]

Are there any matte boxes that will securely fit Cokin "A-Series" 2.5 x 2.5 filters?
Am I also correct in thinking that a 3x3 Matte Box will not be able to hold 2.5 x 2.5 filters?

Don't think in Cokin filters, they are low quality and get scratched very easy, I had like 10 and now are in garbage can.
You are working with Leica optic, don't spoil it.

It's too late, though, as I have at least 7 or 8 filters and I don't want them to go to waste. I like them, and use them with the 43mm adapter, but don't like the hassle of screwing it on and off again, that is why I'm looking for an appropriate matte box that they will fit in.

Anyone else have any other suggestions? On another note, does anyone know of a matte box that will successfully fit around a wide angle lens for the HMC40?
