In years past they were my primary lot and had reliable, frequent shuttles, but just priced too high for me now.

I'd ask if you've considered the airport's own long term lot out by the UA hangars. That might be the best fit for the fastest ride, though at the highest price of everyone ($25 a day). They run full size buses out to that lot though it's pretty close to Park SFO if that works for you.

I know we've had some reports over the years of the airport long term lots being full at peak times and parkers offered a coupon for the same rate at airport terminal lots. Also, some reports of ParkSFO double parking users when they get packed, and you'd have to leave your keys with them. May not impact you if you're not there during major holidays (I'm not - use BART in for those trips).
