I have (2) window AC'S . One is a 5,050 BTU's General Electric ,asking $30. The other is a 6,000 BTU's LG, which has a remote control, and extensions on both sides
for window size, asking $50, Both works excellent.
Were cooling down my 1,000 sf apartment nicely. Most of the time just one would do the job. I have since moved, and now have central air, and have no need for them. Both for $80
