johntbarnett

i'm looking into getting the rm7600s with the psw650 but saw that i could save some money if i went with the rm7500s...does anyone know the differences between the two? i know the rm7600s are the newer model but i can't find out how they differ or what improvements were made. any info would be appreciated!

ps- anyone know if there is a newer model coming out soon..ie, should i wait??
