Thanks all! The SB2 sounds like a great idea! Sadly, I'm going to have to put two (or at least one) of these on my Christmas list, as I'm having too many expenses (including better insulation for the house) right now. Nonetheless, I'm looking forward to buying two of these and having one of them modded by someone. I doubt I'll go the battery route, though, as my Ack Dack is battery powered and it's very hard to remember to turn the darn thing off. If battery switching could be controlled through my Pronto remote, I'd consider it though.
