I think you got a great deal, especially with the refund. I wouldn't feel bad at all paying that much if I needed one (weren't these $950+ retail?), but it's all relative I guess. Hopefully you can get replacement teeth, or perhaps it won't bug you too much months/years down the road when it's sitting on a shelf for a while. And who's to say you won't be able to upgrade in the future...
If the replacement route doesn't pan out for you you could just try filing/sanding down the points from a clear plastic fork to replace the missing teeth. Give 'em a little clear brown wash and call it a day. Not sure if you were aware but the top/bottom front 4 teeth are supposed to be flat anyways, I only mention it since it threw me off when I finally picked one up. Anyways enjoy your new piece...
