Harris Technology on Amazon have it at $260 but only have 4 in stock so I have posted the Amazon Price at the front.
CamelCamelCamel confirms this is a historical best price ever at $260. These have been floating around $330AUD with the best price other than Umart at $289 delivered being $319 on staticice.
With the Australian dollar much higher, the Steelseries Apex Pro Omnipoint Mechanical Keyboard is at its cheapest price ever, $19 cheaper than the previous best ever Umart $279 deal that didn't include delivery so was really $289. https://www.ozbargain.com.au/node/602965
Steelseries have manufactured their own OmniPoint Hall Effect Adjustable Switch much superior to the likes of CherryMX and other Mechanical Competitors. Durability and typing feel is greatly improved. If you don't know why this keyboard is great here is my favourite keyboard reviewer on Youtube Chyrosran22 gave it a glowing review and said it was better than his previous favorite modern keyboard the Wooting One: https://www.youtube.com/watch?v=jfz9TgeZ9m0
Also it has a LCD screen to play gifs and display relevant information on the keyboard!
