I've been quite happy with the servers I'm renting from OVH (http://www.ovh.com/ca/en/) in their new Montreal data center, which is their entry into the North American market; they've operated in Europe for quite a long time.

OVH is a bit more then a VPS, they lease dedicated servers with vSphere or
vCloud.
iWeb is an actual VPS provider, never tried their VPS but had decent
experience with a dedicated server from them for the usual vanity email
purpose you'd use a VPS for now. iWeb B/W is 0.10$/GB and instance run time
starts at 0.06$/hour.
