However there's two options, one that's NIST certified and one that is not - how important is this? Would the non-NIST basically be uncalibrated? It's a pretty big difference in price on the meters, $239 vs $314 so i'm wondering.. ..any help appreciated!

If you buy it for a company needing ISO 9000 stuff or similar Quality 
fluff, then traceability is the way to go. Otherwise - don't waste your 
money on it.

Traceability is a mine-field, and a confusing one too.
