You also might want to check out Empire/Palantir also. It queues up ad-hoc playlists easier than using the remote or front buttons using a Palm device. Any Palm device with an IR port will work, and you can pick up one for under $100, or under $50 on eBay. Most people I show my Empeg to can use it without much coaching, unlike the remote or front panel.
