I appears both Dejibo and Erin have answered the question quiet well for you already. The answer is to simply read up on both products on the Internet and decide which might be the best investment. Since this is really, "found money," you might attempt to get away with the, "but I really don't NEED IT," thinking. I have that challenge a lot, spending more time on indecision than making the decision and enjoying the results.

Conundrum is a very accurate word to describe this situation. Best of luck as I know you will enjoy which ever you decide.
