X-rays aren't terribly hard to produce, it's producing them safely that's the
trick. You might try hunting down a used dental x-ray machine on eBay, the ones I remember
seeing have gone for ~$500. Another idea is using scotch tape in a vacuum to make the
x-rays.

Only way I know of to handle BGA is doing solder
reflow. This can be done with solder paste and a hotplate, Sparkfun's website has
info. The only hitch is that you can only check if the joint is good by powering it up.
Otherwise you need access to an x-ray machine.
I've often wondered if it's practical to build a tabletop x-ray machine for this
purpose. Any ideas how much one would cost?
