Mike,
I'm not 100% positive, but I think the XL-922 was not built for the US market. Most 922s on eBay come from Canada. I have an IPL that combines the 921, 923 and 924, but does not include the 922. You can find this IPL at the orderef site above. I'm not sure of any differences between the 922 and the other models. Most parts will interchange.
