I have also been having this issue but with truggies instead of buggies so no AE product was available.I guess when it all is said and done I would use your head and heart to make the decision not just your heart.I just ordered a CEN Matrix TR and now I'm actually looking forward to trying a different brand.I guess while having a steady diet plan that works is good it can also be fun to try something new.Good luck on your quest and I think that any of the buggies that you mentioned would serve you very well as they are all great vehicles.
