I'm still using
Private Internet Access, USD$40/year. USA owned, but has exit portals around the globe.
It has given rather good speeds overall in the past, but seems to have slowed down some in the past couple of months (using mainly the London UK portal).
Pretty sure it must be owned/operated by some USA agency in order to be so cheap, and the HQ is certainly in the right neighbourhood for that.
Definitely cheap and good enough to start out with if you're new to the turf. 7-day money back guarantee (untested).
EDIT: Heh, I just noticed they now claim to be headquartered in California rather than Virginia, so not in the spooks neighbourhood now.
