All this signal checking crap has finally convinced me to buy my own scope. Big thanks again to Shane for lending me his as it's proving to be a huge help, and helping me learn a ton about how MS works. I'm hoping he'll let me hang onto it for a little bit longer yet until I get the hang of my new scope.

That's what I got. $129 It's a USB based device that you use with your computer (I'll just use it with my little netbook). It's been used by a few of the MS guys and they've all said it works quite well. It's a 2ch Oscope, and a 16ch Logic Analyzer. The software is apparently pretty easy to navigate as well. I heard the probes that come with it leave a little to be desired, so I picked up some better ones off Ebay for $12 shipped.
Someday eventually I'd like to get a true standalone scope w/ 4 channels, but for now this seemed like a great starter unit for a decent price. But in the future, if I could find some old analog Tektronix 4ch sucker for cheap on Craigslist, that'd be cool
