I do have amplifiers although my highest powered one won't quite make 
1500-watts (it will do about 1400-watts) and have had since the mid 1970s.  I 
also agree that having the best antenna possible for one's circumstances is 
correct.  

For casual operation (not contesting or primarily working DX), the principle 
criteria is being able to work, basically, anything that you can hear.  If that 
is the case, then whatever power you are running is, pretty much, optimum.  If 
you are constantly hearing stations but are not able to establish 
communications with those stations, then you do need more power (up to the 
legal limit).  If you are constantly not able to have a real QSO with stations 
that are calling you (i.e. answering your CQ), then you need a better antenna 
or else reduce your transmit power.

It is unfortunate, but, I do hear stations calling CQ, etc., that are ignoring 
a substantial number of other stations that are calling.  Either the receiving 
ability of the antenna is lacking or the station has a high noise level.  In 
either case, that station is an "alligator" (big mouth, little ears).  In 
general, that station is, primarily, just adding to the profit margin of his / 
her local electric company.


Then, there are those stations that can constantly hear other stations but just 
cannot get through.  Those stations are "elephants" (big ears, little mouth).  
In those situations, more transmit power would be appropriate because the 
antenna is not the weakest link.  However, one does need to be careful because 
increasing power also increases the chances for RFI.  Even though the amateur 
radio operator is in the "right" for any number of reasons, one still has to be 
aware of the potential of angry neighbors.  Fortunately, with cable and 
satellite television, TVI is no longer a major problem.  Unfortunately, the 
number of other devices than can intercept the signal because of poor design 
(i.d. shielding) which most consumers are not aware of the situation.  
Therefore, the unwashed masses are enraged because they have spent money for 
devices expecting them to function properly no matter what no matter if the 
manufacturer is the real problem.

Because it feels like "do as I say, not as I do."  A person who owns an amp is 
telling other hams
not to buy one.  If it's so useless, why does the poster have one himself?

If the advice were "put up the best antenna you can within the limits you have 
of cost,
space, permissions, etc. I would agree with it 100%.  But it's often given in 
the context
of "spend your money on a tower and beam, not an amplifier."

I have a take on that, published in our local newsletter recently, and I'll 
post a link here once
it goes up on the web.  It boils down to an in-depth look at the right order in 
which to upgrade
a station, and recommends going from decent antennas to an amp to better 
antennas.

It's nearly always going to be cheaper and quicker to install an amp that to 
put up a serious tower.

Or as someone else once wrote, the cheapest 10 dB bargain in amateur radio is a 
1kw amplifier. The next cheapest 10 db is installing a tribander at 70 ft or 
higher. Getting the next 10 dB after this is very expensive, and few will do it.
