Yes. I didn't see your post until I had already posted. I agree that sniping is the only way to go and saves big $$ in the long run.
This is exactly the point that I was making with my description of "nibblers." You have described the situation with much more greater clarity, so perhaps now others will understand. Again, in fields that are highly collected (where eBay is hands down the greatest source for the items being collected [antiques, especially]), sniping is the only mode of bidding in the community. I've won about 1,300 auctions over well more than a decade at eBay (due largely to the days when I collected antique books and fountain pens) and the value of sniping couldn't be more obvious to me. (Again, sniping doesn't necessarily mean an automated service, it's simply that such a service is much more convenient and the cost is negligible compared to what it will save you.)
