I want a bigish shelter/event tent/gazebo, but don’t want to spend £120 on one. Any suggestions?

My waterproof pop-up gazebo was £60 off ebay, with 4 walls- it’s a bit cheap feeling, tbh I don’t expect the main frame to have a particularily long life, but then I also don’t expect to use it very often. (in fact, I have used it no times at all since buying it, because mates keep turning up with proper eazy-ups!)
