I bought a HM celle and although it was a big step up from my cheapo ikea chair it wasnt anything like as good as an aeron. I eventually caved and bought one of those instead and I dont regret it. You should be able to find one within your budget second-hand pretty easily.
It's an ergodox keyboard. Theyre pretty niche and usually used to relieve RSI (I think?) I've just been using one to improve my posture slightly. It's a lot nicer not having your shoulders caving in 8 hours a day!
If anyone would like a free gopro adapter for a garmin mount PM me. Ordered it from aliexpress but unfortunately it's facing the wrong direction when used with my wahoo.
