Why get a new one? With a little patience and research on Arms list or Gunbroker (or, gasp, a gun show!) you should be able to find an older, Walker trigger 700 in .243.
I have a late '70s production BDL in .30-06 and love mine. I will say though, my buddy has a recent made SPS in .270 and his seems decent enough- both have great triggers, but I will give the X-Mark lever a very slight edge for zero creep and shorter reset.
If you're skeptical of the new 700s, check out the Weatherby Vanguard or Tikka T3. Also can't go wrong with a Savage 10/110!
