Thank you both for your advice. I ended up taking it to a local glass shop and they are going to it for me. It'll will be under $200 - ouch, but doable. We were worried that it would cost twice that. Normally I'd try to do it on my own, but the glass was broken to all the edges and the minute I tried taking it apart I knew it would be impossible to keep it together. In the past when we've had to replace window panes there is usually more breakage before we are done. I'm paying to spare myself more damage. The good news is the new stuff will be tempered and the kids won't be able to break it so easily. Now I need to find some nice window decals...
