http://www.spbsoftwarehouse.com/products/finance/?enSpb Software has released version 2.8 of their popluar Spb Finance software. It now includes full Vista support as well as syncronization with Money Plus, also known as Money 2008.
It requires 2.4MB on your device, either internal or a storage card and supports Pocket PC 2002 and later devices. I believe this is a free upgrade for existing 2.x users, otherwise it is $24.95.
