Yeah you can get <$1 STM32 dev boards and <$4 ST-Link dongles off Aliexpress. At my last job, we kept a big bag of the ST-Link dongles in the office, then whenever someone needed to debug something they could just keep the dongle attached to that board from that point on. It was a lot more convenient than having a single expensive debugger that you had to connect and disconnect.
