I'm going with the sound chip
. They only cost a max of like $1.50, and that is at my local radioshack (yes, radioshack has them. If u're store does not carry them, u can order them online and they will be sent to ur store via free shipping
). I got mine from a member of the forums though
And honestly, it's not that hard, it'l take u only a few more solders to use a chip, so do it right the first time!
