leaking oil pan... need help.

yeap. my oil pain is leaking too .. the gasket is almost all the way out...
today they quoted me about $500 to fix it. they said they would have to raise the motor a few inches or drop the K member... does this sound about right. that is a lot a freaking money to fix a leaking oil pan.
if i get someone to fix it for cheaper. would it be wise to get an aftermarket oil pan? a more efficient one? if so.. what kind, brand, type? thanks..
