AC or LCD?

Hubby and I had this conversation on what to buy next. He suggested AC for the house because it's scorching hot especially at night. I checked for possible AC buys on the Internet and the split-type inverter costs a lot. They it's 50% energy saving but I don't we can even afford to get one. So I suggested a flat screen or that LCD tv with bluray home theatre system. But hubby said it's too much for our little apartment. Or maybe just the LCD tv? We're still talking about it so let's see.
