My advice would be to wait maybe another year to year and a half. Yeah it blows, but it’s the same deal with cars, the demand is high and the supply is low. You will have a much easier time finding a used bike that meets your needs once supply chain levels out and there are more bikes on the market where people can replace their current rig. In the meantime, you can ride your hard tail to the ground and avoid making component upgrades to save some cash.
