Sony’s InZone KBD-H75 is down to $278 ($20 off) at Amazon and Walmart, matching its all-time low. The slick-looking 75 percent board is still rather pricey for what it offers, though you do get an over-the-top 8,000Hz polling rate and Hall effect magnetic switches, which actuate faster than their mechanical counterparts. It’s surprisingly quiet, too, at least in our testing.
