That's really where I burnt the first 4 weeks of this exercise. I would go on those sites, read blogs/posts/product pages over and over, and get overwhelmed and just shut down based on the number of options.
Probably a personal character fault. You're right that it is overkill. And I'll probably be tossing some more money towards SparkFun soon too - but the just from being a pure-software guy to buying/assembling the raw parts just shut me down :-(
