You say you want cheap, but what's your actual budget?
If you don't want to spend too much you'll almost certainly be limited to a springer. IMO best options are along the lines of HW95, AA TX200, BSA Lightening or similar. Also don't forget you'll need a basic scope say 4-12x40 ish, check out BSA, Hawke etc.
My advice is it's better to buy something more than you need right now, because you'll likely out grow a cheap set up. Bear in mind also you get what you pay for. A good starter springer set up second hand should be yours for £200-300 with scope, bag and possibly some pellets if y
