I agree, it's not the cheapest IM app but it is really good and in my opinion well worth the money. One of my favorite iPhone apps for sure.
Yeah it cost more then some alternatives but its well supported and mature software that was on other phones before the iPhone. Works great. Just like I said.. price is a bit higher.
