This looks really exciting and I wish you luck with it. My own experience tells me that these all-in-one tools tend not to sell psychologically. You might get a customer who sees this and wants a few bits of it and is then put off by the prospect of paying for a bunch of stuff they don't immediately want. It may not be well reasoned (the entire package is great value - especially if I know I'll need all of it).

For that reason I think you'll end up spending the next few months playing with your design and pricing until you get a good fit. But again, good luck - it looks like a lot has gone into making this!
