I don't think "pansies" is a good word for it, but I do think many people here are blowing it out of proportion. It is tedious certainly, but no part of the job is actually difficult. I have replaced about a dozen of them, and in most cases, they were people who brought their machines in, were told we would charge them $200 to do it (takes less than 2 hours after you have done it a couple times.. our notebook rate was $125/hr), and they took their machines home to try it themselves... bringing them back in pieces a day or so later. If you are willing to do it right, and (as another poster said) document the disassembly it is very do-able if you are competent working on notebooks, even without detailed instructions. The instructions that are floating around on the web, though, certainly make it easier.. wish I'd had them the first couple times through it.
If you are not willing (or able) to take the time, space, and effort to document it, do yourself a favor and pay to have it done. Read the walk-throughs on the web a few times and decide if you have the patience and attention to detail to do it right. You aren't going to be judged harshly for deciding it is beyond your scope. You will be given grief (or a larger bill) if you tackle it and fail.
My position on computer repairs, especially notebooks, is this: With the right manuals, tools, and advice, anyone who can assemble a backyard swingset can disassemble and rebuild an automatic transmission... but is it worth your time and sanity?
