I have exactly one jump (static line, many years ago), but I did this about a year ago and really enjoyed it: http://www.skyventurecolorado.com/
You actually get to do some maneuvers, which is pretty cool.
Of course if you're just looking for the thrill of jumping out of a working airplane, it won't cut it.

Ps. If you've ever dislocated your shoulder, reconsider. I dislocated mine probably more than 20 years ago and have had zero problem ever since until I went to skyventure. Hurt like the dickens after two flights and didn't do my last fly for fear of dislocating it again.
