I may be heading over to the dealer tomorrow or within a few days to buy my Frontier.... I've been trying to research the pricing online, though some personal opinions from you guys who own Frontiers would be cool. It's the first time I've bought a vehicle, so I'm a bit worried about making mistakes and getting had

(a dealer already tried to sell me a used 2004 Frontier XE for $22k - fortunately I said no thanks and went home to research).
What I'm looking at getting:
2005 Nissan Frontier King SE (new), 4x2, AT.... Power Package, Side Airbags, spray-in bedliner.
I plan to put about $8000 down, and have a pre-approved loan from my bank (4.9%) for the remaining amount. I believe the 2005 Frontiers have a $1500 cash-back rebate at the moment as well (until November 30th). I understand there will also be tax, and a number of other fees (not sure what those are). I live in Southern California btw.
Anyhow, it would be a tremendous help if you guys could help me get an idea of what I should expect to pay for the above or similar Frontier, based on your personal experience. Also any tips you might have on making sure I get a reasonable price would be greatly appreciated
Thanks.
