I'm in a similar position, my N800 can no longer charge batteries. I haven't sent it to Nokia for a repair quote yet but if it's as much as you've been quoted I think it's not worth fixing. Buy.com recently had the N810 available for $180, if they make them available again, you might as well spend the extra $75 for a new device, or put the $108 you were quoted towards a Viliv S5.
