New; Caption, Outrage x, Viper 12, Nitro or L'Edge, Millbrook has a couple nice models for big paddlers too. Used; Encore, Whitesell Pyrahna or Descender, Mowhawk XL 13
If you like the lines of the ME but want it to turn a little faster and be drier you wount hate a prodigy X. If you want to try something with a bit more planing a Nitro will feel loose the first time you try it but will grow on ya, and if you want tight and technical get you a Ledge.
And I think somebody who wants to see you swim (and is probably well under 250 lbs) suggested the Spark! Lots of other good suggestions though, for both current and old designs.
