Wow! Those sold quick! Don't suppose there is any chance of setting the limit even higher to make the boards even cheaper.

Anyway, I don't know about the other 4+ buyers, but I got four because I'm willing to destroy 4 PCM2702s before surrendering and just building p2p tube amps. (The smallest thing you have to solder there is like uhh... a resistor, sweet... of course there is that whole chance of electric shock...)
Though if you are buying 10+ you must either have plans for multiples or really lack confidence in your soldering skills.
