Even with the alleged education discount a Logic8 will still set you back around 250$ and it only has 8 channels @ 100MS/s, the LA used by the article author is 69$ and does 200MS/s on 16 channels, going up to 800MS/s if you're using just 4ch.
The new Saleae Logic MSO looks like a fantastic piece of kit, but their pricing isn't justifiable for an hobbist IMHO.
