AFAIR R-1 does not allow ultrasonic recording.
R-4 does, but it's much more expensive.
The new Tascam HD-P2 records at 24/96 kHz but it's quite expensive, and despite
96 kHz converters, the published frequency response is not very impressive.
Another option is Marantz PMD-671, though some people have complained about
noisy mic preamps.
M-Audio MicroTrack 2496 is cheap and records at 96 kHz, but the frequency
response in unknown. M-Audio did not publish it. Also, be advised that
this unit suffered from numerous flaws - Google for it. Some might have
been corrected by software updates, others most certainly not: like
substandard Phantom Power voltage.
