As Rick says, get yourself educated. You won't be sorry just "looking" for a while. It will save you big bucks in the long run. Unfortunately there are a lot of unscrupulous folks who make their living off the uneducated. Buy the rifle, not the story. You're still ahead of the curve.
Personal opinion; come 2017-2018, people are going to want 'a piece of history' and the M1903 will be a prime candidate (along with the m1917). The 03A3, being WWII, won't see the price increase the '03 will.
