As for the older systems, I would guess around 100. But with near perfect emulation on PSP, I am not sure how desirable a SNESP or NESP or PlaystationPortable is to a gamer....
Older systems are way undervalued. This is an acceptable price estimate for a portable clone (even then it's a stretch), but not for a portable based on original hardware.
If the portable uses original hardware, it should cost more than a portable based on a clone. This is because original systems have a higher power draw than clones, thus requiring higher-capacity batteries, also because most of the older systems require some work to get an acceptable video signal, and finally because most of portablizing involves generic processes such as casework, installing a screen, rebuilding the controller, and getting the system to run off of batteries, which would be the same difficulty level for any portable. With that said, it's been a while since anyone has portablized an older system, let alone sold one, so there is no real benchmark price.
I'm not saying that original-hardware NES portable should have a price similar to a that of a GameCube portable (my hat is off to all GameCube portablizers), but making anything portable has its challenges and there seems to be too big of a price divide. That's my 2¢.
TL;DR - There seems to be too big of a price divide.
