The good news is that the #495 controller becomes a #497 when the firmware is updated. It's fairly common to buy #495's fairly cheap off of eBay and upgrade them to a #497. The Meade cable you need the the #505. A cheap way to pick up a #505 cable is to buy an LPI ($50 from OPT the last time I checked); the LPI (and the DSI cameras) come with Autostar Suite and a #505 cable.
