E3 flasher is a special device to help you programme NAND and NOR flash memory .
It can do both so you know.. I hope you read the main site.. I think if not already they canceled there original product-> do to people wanting a solder-less version .So this is why there was a delay in release date i believe. Now release will be->(10-10-2011 ).
Did you look here & read the FAQ ? http://www.e3-tech.net/faq.html
If i were in your position i would choose this 4 sure ,b4 any other ,flasher.
I would conciser this option also.. The new PCB has on the back the ZIF 50 pin socket installed, to allow a fast connection to the SOLDERLESS tools of PROGSKEET. If i had to choose ,me they are both good !
