Matt, if you operate any 40 and/or 75 meters during the summer months, 1500
watts is very important.  I get to suffer thru trying to copy guys on both
bands during summer on various groups, and those stations running 500 watts
or less are next to impossible to hear.  Of course they aren't trying to
copy themselves so they have no direct way of knowing just how painful it
is.  When operating the low bands during the summer, there is no such thing
as running too much power, Hi.  I recommend getting the biggest amp that you
can physically fit in your shack.

Hi, Butch.  Don't plan to get an amp anytime soon; may want to go up 
to about 500 watts max in the future, but certainly not 1500.--Matt, N1IBB.
