Stop Motion Pro scans a folder/directory on your c: drive for the presence of a new image. It will then automatically add that image to your timeline, meaning, if you can find software to dump a new image onto your computer then SMP will import that automagically.
I don't know if it will do live view though - which is essential for onion skinning. I know when I start SMP I get a drop down of imaging devices to choose from so perhaps it will do a live view for DSLR. Never tried it. SMP has a list of supported camera's and I know its very Canon heavy. I know you're on a budget but entry level is $50 and I'm guessing you'd get value for money as you'd use it a lot.
Edit:
The $50 version has directory scan. The $99 version has directory scan with video assist. I'm not sure what that means as I don't own a DSLR. The upgrade path from the $50 product to the $99 product is as simple as typing in a new software unlock key.
If your camera is a EOS 600D (Rebel T3i, Kiss X5) then live view is supported in the $99 version - which is prolly outside your budget, and full onion skinning for $189 - which is outside even my budget.
The other option is to try the free versions like MonkeyJam but I don't like your chances.
