Host plus beam expanders?

I have a couple 2W blue lasers and I'm thinking of making one with a beam expander. I've been using the survival laser S4 host. I also have one of the stainless hosts. But I'm not aware of any beam expander (5x or 10x) that work with these.

1) Is there a beam expander that will work with either of the Survival Laser hosts? Link?

2) If not, what is a good (available) host/expander combination? Link where I can purchase.

Thanks,
Mike
