I'd rather pay for a code and plug it into my laptop.

Yes, yes it is, apparently. The way I see it, there are basically three kinds of people. People who don't know, and don't want to know how an ECU works. Go get any of a number of big name ECUs, and get someone to install and tune it, and it'll work great and do what you want.
Then there's the people who don't know, but want to know how the ecu works; building it from scratch and tuning it yourself is a fantastic learning experience, and after a little bit, you'll actually understand what you're doing.
Finally there's the people who do understand. Those are the guys who use Megasquirt because of the openness. Want to add a new feature? Build a circuit for it, download the code, modify it to do what you want, and load it on your ECU.
The Megasquirt can be inexpensive because the default hardware is the bare minimum necessary to run almost any engine. Most ECUs are expensive because the default configuration has to support most every engine. Basically, most of the circuits are sitting idle most of the time. I'll freely admit that the Megasquirt isn't for everyone; actually, if you're not sure, then it's probably not for you. But really, we've strayed off from my original point in this post, which was that a lot of people vastly overpay for parts, when cheaper alternatives exist that work just as well... sometimes better.
