These monitors would make great upgrades to any Mac setup from $157 shipped

From $156

No desk setup is complete without one (or more) monitors. I use two 27-inch 1440p monitors for my daily workflow, so I know all about that multi-monitor life. Starting off we have the Acer 24-inch 144Hz 1080p curved gaming monitor in manufacturer refurbished condition for $156.54 shipped via Acer’s official eBay storefront. Normally around $200, this is the lowest we’ve seen it offered. You’ll get all three major input methods here, as well, with HDMI, DVI, and DisplayPort. Rated 3.7/5 stars. Acer manufacturer refurbished items feature a 90-day warranty.

Also on sale Acer Predator XB271HU 27-inch 165Hz 1440p G-SYNC gaming monitor for $599.99 shipped at Amazon. Matched at Newegg. Normally $700, this is a match for Amazon’s best-ever price and the best available. Rated 4.1/5 stars.
