I've never heard them being very low cost. That said, what I have heard
of BGA sockets is: avoid if at all possible. They can be very finicky to
work with. I've heard that you can only put a few chips in before they
stop working.

Of course, these are with chips with many hundreds of balls and at very
high speeds, if these problems exist at the low end I'm not sure.
