I have always been a strat guy and that had alot to do with why I wanted single coil pickups on the archtop. I was worried that gibsoney humbuckers would sound like an underwater buffalo fart through my strat-centric live setup.
I digress. I bought a used chinese squier strat for $75 at SA and did like you and replaced everything on it with the up-brand fender stuff. When I took the pickguard off (it originally had those snarly ceramic magnet pickups - sucked), I found it was routed pretty much from the neck to the bridge - one big hole. I think they call it swimming pool or bathtub. This meant that I could put any combination of pickups in it without having to get out the dremmel.
I opted for 2 chrome gibsoney humbuckers on a mother of pizzavomit pre-wired pickguard from guitar fetish ($35). Since the pickups are cheapies, the output seems to be not terribly higher than the single coils in my strats, so it sounds good through the same rig.
So, I bought the guitar for $75, $35 for the pickguard. I had the original trem that came in my '62 reissue strat, so I put that in. No idea what it would cost. I had some good tuners, so I put them in. No idea what they cost. I used the cover from some dora the explorer note book from a happy meal to make a headstock overlay that looks like a disco dancefloor. I bought transfer letters to put "disco slut" on as the model name. That was like a dollar. Then I got a custom cut decal for it that cost $25 for 6 of them. Actually it was $25 for the first one, and he threw in the rest because it was under a linear foot.
Truth is, I fricking love that guitar. It is new and fresh and really cool to look at. AND the trem stays in tune better than
my real strat ever did. THe pickups have just enough oomph so I can actually sustain notes, but in the middle position, it is smooth and transparent enough for rhythm without changing any gain/fuzztone settings. And I have like $130 in it. At best, it's worth a bazillion jillion dollars, because that's what it'd take for you to get the disco slut away from me.
