I bought a QuanSheng UV-R50 in 2021. You might consider the QuanSheng K1, which is inexpensive, compact, and has better sound quality than the K6. It can also be flashed, making it quite fun for less than 50 yuan. A downside is that the radio reception is a bit weak, and there's some howling when transmitting at close range, which is common in low-end radios.
