FWIW, JMHO etc,
the new lot of 03's and A3's are all USGI, not a Greek etc rebuild, (a lot of guys i know that bought the greeks did not like the black finish etc, however they all shot well)
barrels are listed as crap, but i purchased a 1917 at the north store last summer, that had a very good barrel on it, and looked at several dozen that were as nice (and they were listed as VFW returns with crap barrels)
500+ is not a bad price in today's market, at least in this area, for a good USGI 03 or A3, (and A3 barrels are still available at a reasonable price)
however, i would rather purchase at one of the stores than go for the luck of the draw with mail order,
personally, i think the carbines will be priced all over the range, depending on who made it, similar to the pricing on the 03/A3's
and all will probably sell out quickly,
again , JMHO etc
