Kenny... sorry I didn't respond sooner.
OK I think Jeff's covered the stuff I was gonna say - but its worth saying again.
Firstly, the reason I couldn't really just give you the links as you put it is that it isn't really that simple. You have to also build a circuit - and I can tell you that I've seen one or two different approaches, i.e. slightly different circuits.
OK, for those who don't know, SMT components are the tiny ones you get - resistors and capacitors, and also chips. The chips differ because the legs don't go through the board, they are very delicately attached to fine tracks.
The intricateness of these makes operating on them extremely dangerous. I know, if you are careful you shouldn't mess up. But we've all done it at one point, usually in a stupid way. Anyway, to illustrate how fine it is, say the following is an exploded view
track -- C tip of soldering iron
Basically, the average supplied iron bit is too large for SMT work. Plus, the components can be sensitive to the highest temperature of your average iron, so a specialist temperature-controlled SMT station is desireable. Mess up a custom chip and you're looking for a new machine. That's often done in a PSX, PS2s and Neos are harder.
Basically, Jeff's price isn't just for him soldering a couple of wires to a jack. There's also a circuit, his time and expertise and most importantly, he guarantees you'll end up with a working machine. If you think you can come out with that, go for it.
Now, as for saying his prices could be cheaper. If you can do it, go for it. But what are you gonna do when you come to your first bodge? You're gonna have to buy a new machine :P
