well, if it is just down the road and it is cheap, going to check it out won’t be a bad idea, even just for kicks.
Having said this, Saxgirl had one and tried to sell it (as far as I know, unsuccessfully (?) for £175 on this board )

There are lots of them on offer in the UK because this is a Chinese sax imported and sold for cheap in the UK.
If you want to spend very little, you can check it out before buying and use it while your saxophone is being fixed (by yourself?).
It will never be an amazing saxophone, turn heads, be a good investment and last forever but then it is not meant to be.
It is what it is. Good luck!
