A great HTTP client for testing REST services and all

There are several pretty good HTTP clients on the App Store. I think Rested is the best:
-remembers request headers when you save the request as a file (very useful if youre testing secure REST services and such -- slight security risk as your authorization token could be in the request file, but then its probably somewhere in your files or email anyway, right?);
-gives you the option of getting response as raw JSON or pretty printed (and even syntax highlighted);
-easy to use, with a pleasant, uncluttered interface.
