I believe you can use any standard JFET. Just make sure to match them (read how over at the GEO site), and watch your pinouts.

MAKE SURE YOU BUY ENOUGH OF THEM SO YOU GET A GOOD MATCH

2N5485 is a good sub, 2N5457's should also do ok. The problem isn't just matching the jfets, it's also the vgsoff. Jfets like the J201 and mpf102 have low vgsoff. Around 2.5v-3.5v is good.
