Ask HN: Is Mac App Store worth the trouble for a developer tool?

I make a small desktop app for web developers — for the Mac, and, recently, for Windows too. The Mac version is ready to launch, and has more than 1000 active users (and more than 10000 downloads), based solely on a word-of-mouth marketing. Many users really love it, and I want to start charging money ($9.99).

Here's the kicker: sandboxing will be a pain in the ass with this app, and I also have a plugin system implemented, but not published or in use, because that would be a PIA with Mac App Store too (so I want to launch first and figure that out later). Apple also did not like my icon, which is not an issue, but also a reason why the launch is delayed.

Do you think developer tools benefit much from the App Store effect? Should I simply launch with PayPal payments, or should I not blow the unique chance to build up a good App Store rating on launch (when many existing users will go and buy it over a short period of time)?
