Im from Scotland and didn't know what it meant at the first look, US users are more likely to understand and lets face it they are your biggest market. The hyphen obviously detracts from the value as well. Would appraise at reg fee - low $xx.
As a Bay Area native I probably would have recognized the meaning of it, had I seen it independent of the thread title. Still, I'm not fond of domains that combine hyphens with abbreviations.
