I did have a try with Ni-Zn rechargeables a while back - the big advantage being that their cell voltage is 1.6V rather than 1.2V so a lot of equipment can function much further into the discharge cycle. I've mostly given up with them for the moment - partly because of the high failure rate after only a couple of dozen cycles (at least one of a set of four would seem to loose a lot of capacity) and partly because my local supplier (Maplin) is no more. It might be worth a look if you can find a source of better quality ones though.
