iDoing Head Unit

Hey guys, I’m in the middle of replacing my dash and decided to upgrade the stock stereo on my 21 STI and from reading other post is there an updated version of the unit ?? Also where’s the best place to purchase the unit? I’m in California and I want to get it as fast as possible since I am close to finishing my current project & don’t want to have to wait weeks to get the unit. Any advice would be helpful !

If you guys have other recommendations of stereo update please lmk !
