This is what my LBS has told me, they are avid mountain bikers and from what they've told me, they have all reused them. I was mistaken that they don't sell SRAM powerlinks, of course they do. They DID tell me it was better to use the tool rather than fingers to release the powerlink - though I don't have a chance of getting it off without the tool.

2006 Diamondback Wildwood (gift from my mother-in-law, so I must keep it! It is really comfy to ride)
1996 Raleigh M-20 (got my love for cycling going!)
I have absolutely nothing meaningful to add to this conversation. I do want to say YOU ROCK! You did something new, used new tools, and learned a bunch to boot. How can you beat that?!
