Thanks for the encouragement wv2win. I'm usually pretty handy, although electronics are a bit beyond me. I do at least own a soldering iron, and can do basics.
I will want a standard 510 battery for going out (i HATE people staring at me) so I think a bat mod will be good for around the house. (I don't work, so most of my time is at home anyway). I'm reading the directions for the nicostick now, trying to make sense of them. Thankfully it looks to have been pretty thoroughly discussed. While the terminology is over my head, I at least have a mostly functional knowledge of electronics. (why didn't they teach that in school anyways? sheesh!)
annah, sounds like you've made a good decision to meet your needs.
