The bottom line in all this gear talk is "it ain't what ya got, it's how you use it". 
I know what you mean. However, I find that when I have a nice sound and a lot of sustain I end up concentrating more on the phrasing then on having to play notes/chords all the time because the previous one has died out or sounds bad. Simple arpeggios sound nice when you have a nice sound. I am also more relaxed and ultimately enjoy the whole playing/worship experience more.
I'll tell you this: I've owned Korean Strats, Mexican Strats, Japanese Strats and American Strats. Out of all those I would pick the American Strat every day of the week.
It's a better guitar, period. It doesn't cost more because it was made here...it actually has better craftsmanship, better electronics, better hardware, and typically made to better specifications regarding intonation, pitch, durability, etc...
Yeah, new they cost $750+ these days but you'll probably find that you'll buy it and play it. You won't have to upgrade pickups, tuning machines, the bridge, pots, frets, etc...all that stuff that is typically of lesser quality on the foriegn made guitars.
If I was to buy a lower Fender I'd go for a Japanese and then Mexican but you've got to pick and choose through a bunch of them to find the right one.
For good quality alternate guitars besides Fender, look at Ibanez, Godin, ESP or maybe Schecter.
I know that Rondo sells a bunch of import copies as does Jay Turser and others. While they appear to be a great bargain at first, my experience with them is that they lack quality and long-term-use durability that will cost you $$$ in the future.
I really like Godin guitars. You'd be surprised at what high quality you can get in their axes at such low prices.
www.lasido.comThe Freeway and Detour guitars are killer deals for the money. And quality that surpasses anything Korea or Mexico can manufacture.
I'm not trying to put down folks from other countries nor their work but I've been playing for 26 years and hope that I've learned a couple things about what makes an "ok" guitar and what makes a "good" guitar.
You don't have to spend $1000+ to get good. Sometimes you don't have to spend $500.
And sometimes, as in the case of my Solidac, a really good deal on an exceptional guitar comes around. It's a blessing when it does.
