Alternatives to Flex Spending Account?

My wife and I have pretty much had it with FSA. They request documentation for every single charge we make on the card and recently froze our account because there was a miscommunication about what documentation they needed for a partial co-pay of $9.75 for a pediatrics appointment.

Now with them lowering the max per plan year to $2500, I'm just not feeling like the pre-tax benefits are worth the hassle unless we are planning for one or two large medical expenditures. So, my plan is to set aside a couple grand for 2014 in a regular savings.

My question is there anything smarter/better that I can do? Are there any private alternatives?
