I'm looking for screen cap software that will let me save screen shots as *.jpgs in a folder of my choice. For simple screen shots, I really don't want *.png files.

Hopefully, it can be invoked by a couple of keystrokes that bring up a "lasso" to capture the area I want and then save it.

Any suggestions?

Thanks!
 
Already built-in. Screen Capture does what you want.

To change the default format for screencap images, in Terminal.app, type:
defaults write com.apple.screencapture type jpg (or whatever type you choose)​

To change the default folder for screencap images, in Terminal.app, type:
defaults write com.apple.screencapture location "/Users/~/Desktop/" (or whatever path you choose)​
 
SnapZPro, without a doubt. Ambrosia has been developing for the Mac for more than a decade and IMHO all of their stuff is well-thought-out and very effective.

SnapzPro lets you use a hotkey combination of your choice to bring up a dialogue and you can do screen capture, window capture, selectable capture (i.e. your "lasso" concept), or even video capture. I use that last feature a lot. I can capture any video on the screen no matter what file type and save it as a .mov.
 
You can also do cmd+ctrl+shift+4 which will put a cursor on your screen to drag out over the area you want captured. The capture goes on to your clipboard which you can then paste into preview (or any other graphics prog) by doing ctrl+N. Save in whatever format you want.
