Welcome to the forums jopela! Your now on a very addictive search that is fun, and can be expensive or not, yet rewarding all at the same time.
Most forum members would say to audition and pick your speakers before you buy a receiver. That way if you get some demanding speakers, you can pick a receiver that can power them.
We are all here to help, but we have to get personal and ask your budget and how much gear you expect for that sum.
We caution people to stay away from Circuit City and Best Buy, as they have nothing you can't find on the net for a better deal, and they really don't carry speakers that are worth what they ask for them IMO.
Have fun, and take your own CD's and a note pad with you when you go speaker shopping/auditioning. Jot down notes on different speakers, likes, dislikes, etc.
Many good speakers can be found online by Internet Direct companies that will allow you a 30 day in home trial. Just ask and we will post links. I bought everything in my signature online except for my TV!
Most of all HAVE FUN!
