Of all the ones I've used, I like the IC-746PRO the best. It has a RTTY 
filter mode which provides a twin peak filter, 300 Hz bandwidth and 
amplitude limiting. It's DSP IF system is superb. Another good one is the 
Kenwood TS-870S, likewise with a superb DSP IF system, but without the other 
bells and whistles. I also had a Mark V FT-1000MP Field which is acceptable, 
but not in the same league as the two above.

I presently have an IC-756PRO III on order, which I bought mainly for the 
spectrum scope. It has essentially the same IF system as the '746PRO. If it 
proves to be as good, then it would be my top choice.

Bottom line: DSP IF filtering is a must. Crystal filters are history. Good 
crystal filters are expensive and DSP can do the same thing or better for 
pennies, relatively speaking.
