i changed the batteries in my wavebird thrice in the 3 years i had it, once the month after i got it [cheap crap cells nintendo sends with it] and then about once every year,... haven't used it much in the past 7 months though.
wii sports, play, excite truck and ssx are fine on the wii remotes batteries, i seem to get longer than the 60 hours nintendo says... Re4 i reckon i have to change about every 30 hours, so thats in keeping with ninty.
LoZ;tp however runs them down really quick, must be less than 25... maybe its cos i use rechargables.
as for re stocking wavebirds, if they are selling for that much maybe it would be a good idea... though if nintendo have stopped production they might not have the dies, appropriate assembly lines anymore.
