Thank you to everyone for all of your thoughts and suggestions. After reading all of them as well as many other reviews on other online forum boards, I've decided to just spend the extra and get the Flex or else I'd probably be kicking myself later for not. Realistically, I may not need to spend the extra, but the difference in price is simply one regular detailing job, so why not? With the limited use it will get (at least to start) it should last me a long long time. Thanks again to everyone.
