Do Most Cf Gps Cards Work?

[xamindar]

I'm looking at getting a gps card for my zaurus.  But I can't find any information about which ones work and which ones don't.  I have found that qpegps's site lists qps units that apparently work with qpegps but I'm not sure if that means they work on the zaurus.  Can anyone help clearify this?

I know the pharos cf gps works, that's the one I have.
