Remember that if your prices are too high you can always use tricks to "lower" it, like offering time-based discounts, affiliate programs, coupons, etc..
Then people feel they're getting a deal -- some will buy because of it -- and others will pay full boat anyway.
I agree with Alain that we tend to under-price (+1 to you my friend), but note that our v1.0 products are full of crap and probably need to be cheaper. As we improve the product and raise the price it works, but some of that might be the better v2 or v3.
