Depends. Are you wanting to shoot a lot more paint? Electronic frames have a much lighter pull which will make you run through your paint a lot quicker. Are you wanting to shoot in different modes (3 shot, full auto, psp, etc?) Are you a person who wants to upgrade your guns? A lot of people do as much as they can to a marker, then either set it aside for another model or sell it.
Personally, I say it's cheaper to buy an electronic frame and slowly upgrade the gun you have, and there's absolutely NOTHING wrong with doing that. However, IF you do get an electronic frame, make sure to buy an electronic, agitating loader because you will definitely get chops!
