I noticed a lot of Seagate 8GB CF drives for less than $160 nowadays, and decided to pick up one.
It works OK in my SL-C1000, and having so much space available for games, music and movies is nice.
A lot of them are selling for $153. Just browse http://search.ebay.com/8GB-seagate-CF and chose one.
NB : This drive can also be purchased on Amazon for $150 shipped if you live in the US : http://www.amazon.com/gp/product/B000BO0SG...282452?n=172282
