Don't know if it was mentioned before but Bose has an offer on their website, something like ...

They will loan up to $2300 towards a PAS purchase with 0% interest, to be paid back over a max period of 12 months thru your major credit card, Visa, Master, etc.
A charge is made to your credit card each month.

Not bad if you really want one and you don't want to lay out all the cash at one time (before the holidays)
