Waiting 'til the last minute is usually a workable plan - I know it's the one I use! Far as the AF100 being sold by users, I guess I have two ones: One, they are def being sold in higher numbers then the FS100 (which I've only seen one of so far), but the AF100's been out for about 6 months longer. Two, the AF100 certainly isn't going for a "bargain" price - it seems to be retaining it's value, maybe going for (on average) of 85% of it's retail value.
