I have the SK41G (AMD, AGP one) and I love it. I didn't think it was that bad of a deal either. I paid $309 shipped from NewEgg.
It works great and is very quite (contrary to popular belief).
As for the SN41.... It has been said that it will be around $100 more expensive than the others becasue it is new and because it has a Geforce 4 MX onboard.... so expect to pay $400+......WHEN it finally comes out. (Remember, it was supposed to be out at the end of November)
