These things tend to be more geared (sic) towards the guitar collector types than towards someone after something cheap & cheerful.
There may be some deals to be had, but for something a bit "road worn" / "player grade", IMO, you're best off scouring the For Sale ads here, Gumtree & FB Marketplace (locally to you).
Guitar shows are a nice way to spend a few hours, nerding out at what's on offer (whist baulking at the prices).
