[ICOM] IC-910H is not worth the money. Or is it?

Hi there,

I've been looking around for a new (new as in brand new, not new to me. :) ) rig that would deliver more serious power on UHF than the 20 Watts I get now from the FT-897.  It seems that the 910H is the only serious contender in the VHF/UHF weak signal market, but $1300 for a box that doesn't even offer stellar performance? I can't imagine Icom is selling many of these as it seems way to expensive for what it offers.

For $300 more I can get a Kenwood TS-2000 that offers 50Watts on UHF and includes IF-DSP and satellite operations. It even has a sub receiver for some AM/FM/packet work.

Even the IC-7000 with 35 Watts on UHF sounds like a much better deal than the IC-910H. 

Sure, the IC-910H offers dual RX and satellite operation, but for what it is and offers, the price should be way below $1000 by now. 

73,
