" I recommend the MetroFi 220's to anyone. Although they do carry a somewhat hefty price tag, they are worth what you pay for them. At the moment, they are on sale at Dick Smith’s for $68, which is down $30 from the original price of $98. Even so, at $98, I still think they are quite reasonable."

RRP: $67
