I started with Mobipocket and found it to be painfully slow. Then I tried Plucker but to be honest with you, the set-up hurt my brain. I don't want to have to do all that work. Get it on my Palm, that's all I want. Somebody on my state association board recommended Cachemate and while I hesitated in spending more money on a program that may or may not work, I am very happy with it. I like how it easily works with GSAK and the money was well-spent. It's so much faster than Mobipocket and the set-up was very simple. Just my opinion, but I do like it.
