box type air conditioners

despite the move to split systems, i seek to upgrade the 50 year old 10,000BTU frigidaire with another box system.

i'm having a hard time finding a large capacity example of the 428x660mm variety. so far, the kelvinator KWJ62HRA seems the most appropriate. has anyone any opinion to offer regarding the kelvinators? evidently fujistu no longer imports them due to government regulations relating to efficiency requirements, so they are becoming increasingly hard to find.

any reccommendations for a 2.5hp+ box system would be much appreciated.


regards,
