Had issues finding deals yesterday too. Try these:

• Used Canon EOS R6 Mark II Mirrorless Body has dual slots.
• New Canon EOS R8 Mirrorless Body is cheaper but battery life sucks.

Honestly, since your 5D IV just bit the dust, you should look into the Canon Loyalty Program. In my experience, this is the best kept secret for getting fast discounts when you are in a pinch. You literally just call Canon support, tell them your old camera died, and give them the serial number. They usually offer around 10% to 20% off refurbished or sometimes even new gear. You could easily snag the Canon EOS R6 Mark II Mirrorless Camera Body and stay well under that 2k limit. Plus, their customer service is super fast and they can overnight it if you explain the situation with your Chicago gig. Definitely worth a quick phone call tonight before you waste more time refreshing retail sites.

Over the years, I've tried many buying strategies, and retail discounts on new bodies during Black Friday are usually disappointing. I was in a similar tight spot last year when my main workhorse failed right before a multi-day conference. I ended up going through the manufacturer's direct refurbished store instead of the big retailers, and it saved my budget. Here is what I learned from that experience:

• Refurbished units from the official store undergo much stricter individual testing than mass-production retail units.
• The shutter count on the one I got was under 150, basically brand new.
• You still get the full one-year warranty, which is crucial when you are relying on it for paid gigs. Definitely check the direct refurbished store tonight. They usually restock randomly, and the discount on my current setup was way better than any holiday retail sale.
