This type of relay would work depending on the coil voltage. However
I would guess that voltage is also 120 volt.

What I am trying to do is have the ability to switch 4-5 different
lights (150-1000 watt) from several locations within the same building
without all the hassle of 2 and 3-way switches.

My plan is to have a relay bank that these lights would source from
(total wire run of 60-75 feet) then have small low voltage/current
pushbutton switches activate the relays. 4-5 small pushbuttons could
control any light in the building from that location.

I have thought about X10 but have also read more bad than good about
the wierd things they do or don't do.

I'm looking for a source of new latching relays.

Coil needs to be 12 to 24 volt and contacts of 10 amps at 120 volts
AC.

The X10 Appliance modules contain a latching relay. At about $10 a piece
this might be your best choice.

The last time I looked at one of these, what I found wasn't a latching
relay in the usual sense. It's a solenoid which drives a rotating
two-position switching thingie. There isn't a separate "set" and
"reset" coil.
