Should You Get an efunda Account?

[bill nye scienceguy!]

I'm thinking about getting an account on efunda (being sick of getting halfway through something before it locks me out). Does anyone here use efunda and think it's worth $36 for a year?

It is only 36 bucks. How bad can it be? I would spend the money, try it out, and then make a decision to renew my account. If it isn't worth it, then don't rejoin.

Thanks
