new clutch question

So first of all.. I went to the auto shop on the navy base I'm stationed at and he quoted me at just over a grand for a new clutch. I asked why so much and he said it would be 658 just for the labor! Ridiculous! I'll take it somewhere out in town and have them do it for half the price.

Secondly.. i asked how much the clutch kit was and he said 300 from the dealer because that's the only place he could find it. He then explained to me that the dealer said they have a "redesigned clutch" that Nissan made for our trucks because of recurring problems with them. Does that sound right? Does anyone know a different route I should be taking? Please help me out. I could really use some guidance because my wife is 25 weeks pregnant with my first son and I really don't want to spend that much. lol

p.s. my truck is an 06 CC 4x4 6Spd
