In one of my Damark catalogs there is a Carrier portable air conditioner
very similiar to the Toyotomi.  The good news is that it is $499.99, factory
serviced, compared to the appr. $679.00, factory serviced.  The Carrier has a
larger cooling capacity, 5700 btu/hour, compared to the 4000 btu/hour.  The
dimensions are 33.5"H x 17.5"W x 14"D.  The Item no. in the catalog is
b-9090-613679.  Their number is 1-800-729-9000.  All the usual disclaimers.
Hope this helps someone.
