Microsoft repairs xbox extremely fast - Common?

So let me fill you in with my story here, I called Microsoft Jan 17th about my XBOX (I had the E74 Error 1 red ring, but it was unfixable basically graphics card fried or whatever) Anyway due to sunday and MLK day I didn't receive my coffin until thursday 2nd and send to UPS the sameday and microsoft received the xbox sometime sunday night. So I wake up today on tuesday morning and my status shows it's already been shipped back to my house and shoud arrive tommorrow around 3.

Is Microsoft getting their **** together finally and making quick turn around's or do they treat E74 error different from the 3 ring RROD?? I did read most people with E74 wait for at least 3 weeks.

Did any of you have a fee after the repairs?

Lately I've had the 3 rings a lot. But still get it to work. But it takes a lot of times of putting the disc in to get it to read a game.

It pops up with that white screen telling me to put it in a 360 system often. So I know it is going to die on me soon.

But is there a chance I'll get charged?

I dont remember where my receipt and warranty info and all that is. Does it matter?
