JFM I was intrigued, I downloaded it - and I like it! I cannot claim that I use it on a daily basis, sure, but each time I have used it, I have been pleased with the results - and I found it to be very easy to use.
I don't think one can complain about the price: since obviously the market for such an app is not very large, it is legitimate that the developer charges accordingly, otherwise his income would be too low.
