I have an IOBlix and I love it. A long time ago I had my old Epson 600 hooked up to it and it was very fast.
Now its just used for downloading from a digi camera and hooking up to a modem for faxing. I got 115K with no problem over the serial ports.
I also have the add-on ethernet card which works great!
It even comes with a Zip mounting task. (Although I only have an SCSI one so am not sure what its actually for but it comes with a dos driver for a Zip drive)
As for the multiface, I hear its a good card but never used one myself, although Ive used other serial cards and tbh they are all easy to use and Ive not had any problems with any Ive had.
