Alysum said..Thanks I've now realised the mystic and slingshot are the same as wmfg's first version. I'll snap one of those

I think you'll find the mystic the same size and design. Ozone, Slingshot, & others are same design but 1 size down. (Not as tall) having said that, I don't use the full extension (stroke) of the WMFG so all the others would work just as quickly. Look at hoses, bags? and wrap up of each to select what suits. Some nozzles pop off and some brands don't work well on others. Ask the retailer.
