Hatsan are worth looking at, they are a Turkish brand, nice stocks, generally well regarded by those who have shot them, though looked down on by those who haven’t. The 900x Breaker is about £120, there are a few models in the Hatsan range sub £200.
The first air rifle I has was a SMK XS-20. It was a good gun, the only reason I passed it on was because I was concentrating on .177 and the XS-20 is only available in .22.
