Best health care plan with an HSA

My employer has tasked me with finding an extended health care plan for myself and my coworkers.

Concenscus is pretty simple. Basic benefits and dental; and many people are asking for a Health Spending Account (HSA).

The first two should be pretty simple. I reached out to Pacific Blue Cross and the rep I got said that most extended health care (including them) don't have plans with an HSA. I find it hard to believe, but figured I'd throw it here.

FYI: No real budget, but I think we're aiming for $250 or less per a single person.
