hard decision. I don't consider PENG to be as good as PE as it is now. But
1) since the 3000 replaces the 2000 there are more chances that features will be added to PENG then PE
2) They offered PENG when we were asking for it so that we can start looking at changing our CCFs to PCFs, so I think PENG might actually be a prerelease, and the next version of PENG might be more complete (PCF files look more like NCF files and PENG more like NE, so anything that was in PE but not in PENG might just be that it was not added yet, and not that they have removed it.
3) the 3000 will supposedly have some cool new features and has more hard buttons
