I just got this message from Steamed, and thought I would share in case someone else is thinking the same

To begin with, make certain the image itself is on its own layer, and is not set to being the 'background' in Photoshop. With your image as a layer, and not a background you will begin the work of clearing the unwanted stuff from the character.
#1 - Get to learn about the pixel color tolerance setting on your wand. That you can control how much or how little color variation is selected per click. Remember to hold down shift (might be control, I forget which, but my fingers always remember) as you click to keep selecting areas until you have as large a space you want. You can change the tolerance with each click/selection. Higher tolerance = more color ranges that will be selected with the wand. A tolerance of 1 is the lowest, the most I ever like to work with is around a 10 to 15 range for big areas.
Once you have your BACKGROUND selected....
#2 - Feather the selection. That you will want the selection to have a feather variable of 1-2 for a nice clean removal. A feather that is more dramatic such as 10 - 30 adds a great blend effect.
#3 Hit delete, clean up the image. There usually will be some small TRACE left. A GREAT way to get -all- left over trace you missed is to add the 'STROKE' effect to the layer you are working in. Stroke will create BIG obvious outlines even on something so small as -1- pixel, which makes clean up super easy. Once you are done with background cleanup, remove the stroke effect from the layer.
#4 Perfect the character. Use a feathered eraser setting for this. You never want to use a hard line eraser. Feathering the images makes them softer, and seem more natural.
Enjoy
I hope this helps you with your sigs. If you want a screenshot tutorial of my work, Ill be happy to write one and post it with screenshots!
My average cutout time is 10 - 15 mins for a "messy" job. Some jobs, are as fast and easy as 2 mins. This style is pretty fast, I never use a raw eraser for the job.
PS - Experience, error, and college has taught me all I know
