A 1M serial number range Garand has probably been rebuilt several times by now, and is unlikely to be in "correct" configuration. Unless you can disassemble the rifle and verify the drawing numbers on all of the parts to certify that it is in "correct" configuration, I would not pay a premium for it. $950 is high, unless it is WWII production and has all matching parts. However, a WWII rifle with all matching parts is likely to be a poor shooter (very worn barrel by now).
You won't regret a service grade from the CMP. I recently purchased Springfield service grade from the CMP--it's a 1950's production in great shape for $595 + shipping.
The $595 CMP rifle is what you would expect to see in a store for about $750-$950. They don't send out beater rifles in service grade. It will show use, but not be a beater. A really worthwhile collector Garand will probably cost more than $950 anyway.
The CMP purchase qualifications look tough on paper, but it's really no problem to qualify. If you have a concealed weapons permit for your state, then you are already halfway there on qualifications (the marksmanship participation requirement). If you don't have a carry permit and don't want to shoot a match, get a Curio and Relic FFL ($30).
For the club membership requirement join the Revolutionary War Veterans Association for $20 or the Garand Collectors Association for $25.
If you are active or retired military your military documents qualify you on both requirements.
Get the order form notarized at your bank (usually free) and send it in. Your rifle will arrive at your door via Fedex in 60-90 days.
Additionally, if you live anywhere near Port Clinton, Ohio or Anniston, Alabama, you can go to the CMP store and pick out your rifle yourself.
