I imagine they're all from the same source, but which one would be better to deal with?

Century: Comes with Bayonet & Scabbard, sling, cleaning kit, and pouch. Condition: Excellent.  $139.87.  Shipping: $12.50.

SOG:  $109 plus $10 handpick, I'm debating on getting the turned down bolt for another $10, so up to $129 total.  They don't state whether the accessories come with it, so I assume they don't.  Condition: Very Good.  Shipping: $??

If I take the turned down bolt out of the equation, would I be better off trusting Century to send me an Excellent rifle, which SHOULD be better than a hand-picked Very Good rifle from SOG?  Plus I'd get the accessories?  What should I do?  Does Century allow handpicks for items like turned bolts?

Ugh, never mind... Century is out of the Excellent AND the Very Good grades, and SOG is out of the turned-down bolts - and they don't come with the accessories kit.

Neither Century of SOG are on my "A" list of C&R suppliers.

That's just my opinion and worth every penny you paid for it.
