I purchased a VGA-Power-Sync cable made by aximsite member ChrisMax more than a year ago. Works perfectly. I used it as my primary charging/sync method for a while when my cradle broke. Don't know if they are still selling,
but check this thread out.
The AXIMPDA one looks well built and "cleaner" with the embedded mini-usb connector. The one by ChrisMax has the DC in and Mini-USB on each side of the cable on the Axim connector side. Looks at the pictures at ChrisMax's ebay store.
