What parts should I start with?
For an A1 build, I'd start with finding a barrel (C MP B, C MP C, C MP CHROME BORE), as they are what's drying up the fastest. I'd then go for the upper (C H or C K marked, but supposedly a no forge code upper could be used for an early A1). Everything after that should be rather easy to come by.
Edit for grammar.
^^^^^+1!^^^^^^ The barrels are getting harder to find, and will be the most expensive single part. CH or CK upper recievers aren't growing on trees either. But a NoDak Spud A1 upper is a fine alternative. It will also match (color-wise) your NDS lower nicely. The CH/CK may or may not.
If you want it to look
really nice, you'll want to get your slipring, mag button, trigger guard, buffer tube, and charging handle re-finished by USAnodizing.
Get a DPMS LRPK and do the "naval jelly" trick on the trigger, bolt stop, pins, etc. Then buy the nicest set of furniture you can find. Any modern BCG will do, as well as modern buffer, spring and tube.
Then try to find an A1 ejection port cover in good shape!! Don't forget a set of A1 sights (font and rear). Sling swivels...
Are you sure you can't save up/hock something to raise the $600?
