The deal with both HSA plans (the ones with the lowest per paycheck premium deductions) is that you pay for all your healthcare upfront and then after $3500 on the one they will pay 80%, after $4500 on the other they will pay 100%. If your family is planning on a baby or any surgery, the out of pocket on all plans including the POS comes out about the same (about $6500 with premiums and/or copays). If you are planning on 2 major events (like a baby and a surgery) the POS plan sux and could run you well over $8k in copays. The company (Aetna) sux, and it is in my estimation number three on the list for 85% of the pilot group-- with only pay and duty days coming before it... No matter which plan you choose, you are forced to take a gamble and hope you chose the right one... Coverage from Greatwest (2005) is pretty much a wash on paper, but we've yet to see what kinda of games Aetna will play that they are famous for...
My wife's job had Aetna for a 3 year contract and were so itching to get out of it they paid a penalty and went to United Healthcare. Which also reminds me, if you choose the HSA and your wife has a plan, they require hers to be primary, (or so she has been told by her job) which makes the plan useless unless you're in too bad a shape to qualify for your medical anyway...
