I have looked at all three. One nice thing I like about ARC250 is what
appears to be the ability to cut frequencies off the web or text and load
them in. I have to look at it a little more. The web site Frequency of
Nature looks like you can do this. I also get the Monitoring times online
magazine sent to me and this would be a plus.

The ScanCat software has been around for a long time but I feel its a bit
pricy for what it doses. The E-scanner plus software I think is also pricy
for what it doses. I also see that Uniden released the control codes so it
probably wont be too long before people write their own.
