or wait for the JR-Programmer 2 witch was stated in other posts that it would even be faster with a faster read/write speed, if I remember reading correctly. this would replace the nand-x as they dont have the source from Tiros so it says at 3.0 & with JR-Programmer & JR-Programmer 2 the code it's all Xecuter & can be updated & tweaked & updated when needed or when new products come out & firmware can be made to work with other mods Xecuter makes. nandpro is used with nand-x v1 & v2 so it's limited to what nand pro does with version 3.0
I would keep Nand-x V3 & JR-Programmer 1 & or JR-Programmer 2 when it comes out.
Nand-x are used with nand pro software, as they will not be able to keep up with the newer products Xecuter creates in the near future

or will be limited in what they can do. USB-PRO V2 + JR-Programmer 2 will be what everyone owns by end of summer or by fall time this year.
USB-PRO V2 + JR-Programmer 2...
These 2 units will replace Nand-x, USB PRO v1, XECUTER CK3I or CK3 lite.
