depends how much you wanna spend. get a scsi to ide bridge, a cheap ide2compact flash adapter off ebay (i got 3 for £1UKP + £3UKP postage), then you can plug in off-the-shelf CF cards and enjoy silent computing, zero seek times, a cooler running system and with less strain on your PSU. :-)
for anything 4Gb or less, i don't really see any other alternative these days..
