what I want is a nice, troublefree shooter
That is nearly impossible in the Garand world. I'm not trying to discourage you, honest--but an M-1 requires a fairly high degree of knoweldge and an intimate familiarity with the design and function of the weapon. To do otherwise is to risk doing some $$$ damage to a fairly high-dollar weapon for which parts are getting scarce or far worse--finding out that .30/06 is a lot of power up near your cheek. A good place to start IS the CMP -- go do a shoot if you haven't done one. Pick up one of the many books on the Garand and do some reading.
That said, get an m-1 from CMP and spend some fun days tearing it down and 'playing' with it. Myself, I sort of fell into the Garand universe at age 19 and made some expensive mistakes (blowing out the gas system with the wrong ammo being one). For me, the 300.00 M-1 was a poor substitute for an m1a that was about 850.00 at the time. Knowing what I know now, I wouldn't EVER think of foregoing an M-1 in favor of any other infantry rifle.
You will get sucked in--be warned!
Good Luck!--Mike B.
