There is, at least for the short time, a limited supply of those Birdshead Vaqueros. Although, it could be that their popularity will mean more of them to come, my point is that if you wait long enough, your choice will be made for you. If that happens, you'll get over it and find something else that catches your eye. If you do take the plunge, I doubt you will regret it, based upon my own experience, and would likely have little trouble selling it later if it doesn't suit you. It's a niche piece that not everyone would want to buy, but being a limited item, those who would want to buy it would likely want to buy it with some seriousness (not saying it will appreciate in value, just that it shouldn't be too hard to sell).
