Yep that's my DH too Hestia, ridiculously hard to buy for. I think in all honesty he's going to get the drop saw anyway, and with the work he's doing he'll need it sooner rather than later. But then it kind of seems like it's not very birthday-y, he would have got it anyway and the occasion doesn't matter.

I think I'll keep looking for something small that can go along with it as something special from me & the kids.
