IRDA hardware for Linux

I know there is (some) support for IRDA under linux, and I just wanted to know what people's experience on this list was for the better supported hardware. I am looking to get a USB to IR adapter (to use with PDA, etc...) Any hardware recommendations? Any HW to avoid? Thanks, Babu __________________________________________________ Do You Yahoo!? Yahoo!
