got a potential buy on factory NIB 320RX @ $800 negotiated with 'original purchaser' who had sudden need for funds for other priorities.

Is this a decent deal or not?

Cabelas a month ago would sell me one for "$750" but they were out of stock, no ETA for replacements.

I got mine at Cabelas for $700 when they had a SIG sale a few months ago. My local gun store had them for $750 which also seemed to be the going rate on the interwebs.

They seem to be a vacuum of them on the market. If I really wanted one I'd pay the $50 premium to get it then.

Personally I'd wait for a better deal unless you absolutely have to have one right now, or if you're trying to do a friend a solid. That $750 probably would have been +tax, so there's that to consider.

Cabelas gift cards can be had regularly for $80 for a $100 card so you can get a killer deal if you have patience.

I purchased mine from Cabela's (two tone full size) last August and paid $720 plus tax for a total of $774.

$749

I got mine about 6 weeks ago from Cabelas for $750. I think list is $800. I did not see any others available online for anything less than the exorbitant prices being asked for on Gunbroker.
