Hi; I have found this thread rather interesting since when I get antennas up next spring I will have a similar choice. I may be incorrect but after you add two filters and the microphone adaptor there isn't as big a price difference as there was between the two rigs. I think I once decided it was about $400.00 My real considerations would be the quality of the hf receiver and whether I want hf uhf and vhf all in one radio? Since many folks may al ready own a 2 meter radio they may or may not want to duplicate things. From what I have been told I'm not certain the increased accessibility is a real concern. The fact that I hear a number for the mike gain setting is a nice convenience but counting worked well with the 570. Richard
