Hi,
I'd recommend trying a Linksys EC2T card. I got mine at Microcenter for like $30, and while I had a few problems with it & my old Commodore MoBo at first, such as the system resetting when I'd insert it, ever since adding the following two lines to my Startup-Sequence (right after my 4xEIDE & setpatch stuff) it's been crash-free.
C:CardPatch
C:CardReset AUDIO ON
(Both of these programs are available on Aminet, running them together seemed to work better than just CardPatch alone)
