I'd say It would be nice if you do some search on your own, flashers aren't fool proof and while we can try to help you, you should try to get as much information as possible before buying one and attempting to install It.
By looking at this I'd say the limited version might be worth It. It seems to be more newbie friendly, you got the NOR clip there and some tools/cable that I'm not sure if It comes with the regular version.
The E3 will work with your model. I have one myself and installation is easy if you follow the steps accurately. However the quality of the clip is questionable and you'll need to be careful the pins don't get messed up.
Note : the limited edition of the flasher includes the esata station. If you have an esata station or drive already you can get the normal e3.
