Hi Devon , I agree with Astronobob , try them both first on the moon and jupiter as these are real easy to find and then make a descision , personally I would go for the Saxon , it has a longer focal lenght and will , in most cases be a better mirror ( its easier to mass produce a longer focal length at a better quality than a short one ) .
And 1/3 an inch is not really that much .
My 5c worth .
