I don't know that there's a reason to buy the cheapest one out there if you plan to use it longer than these speakers. Buy what you can afford and think about the fact that if a receiver is selling fro a really low price, there's a reason for that and it's not necessarily a good thing. Best to define how you'll use it (mainly movies, music, connection to a computer for streaming, iTunes/iPod, etc). If you want loud, you'll need power- there's no way around this.
