www.sedo.com seems to come up alot..
As far as cybersquatting, as long as you aren't grabbing a domain that would actually be for the product / person / company in question it's fine..
Like if you registered appleipad.com that would be squatting, but if you did ilovetheipad.com and had a real site dedicated to iPad news or something that should be fine.
http://justanotheriphoneblog.com for example.
Otherwise Calgary could take away our domain.
