Ah crap, maybe I will just do it.Tim
Ah my name is Tim as well. 
So from one Tim to another: Thanks for the detailed information involved as to the concerns with the timers. It's helpful for me to learn more about this as a beginner to the Arduino world.
At the moment, I'm mostly trying to figure out how to use your library without conflicting with the SD library's use of the 10 pin as a selector (per: SD - Arduino Reference) Based on what I've read there, though it looks like I may be able to just use SD.begin() to select a different pin for card initiation, and as long as 10 remains an Output that shouldn't actually cause problems.
So actually, with a little reading, I think the library will work for my particular application as it is.
Though I still think it would be awesome to have versions of the library for each of the available timers, just for that extra flexibility. From the pretty robust response you've received on the library in only a couple weeks, I think it's clear that people are finding it useful.
Anyway! Thanks for your efforts.
