My choice would be either a Profiler or Grill. Lense changes on both are a doddle (current world record holders at 4.78 seconds for the Profiler), and the Grill has a party piece- interchangeable foams. Plus you also get the standard V-Force thermo-cured anti fog lens.
I don't think V-Force make the normal Profiler anymore, but the Profiler SE's are better. The colours are reversed, but the SE blue is much better looking IMO than the standard blue. Also, the SE profilers have improved lens clips that hold the lens more securely. Plus, there is now an Olive Profiler, Camo Profiler and a white Profiler.
I'm not too sure on the Grill prices, but the Profiler SE's go for around the £60 to £70 mark.
Hope this info is of use to you.
