Recommendations for 1000

Just the drivers. Thanks.

The room is a long skinny room around 50' by 25' with cement walls. Mostly used for music but also needs to work well with movies. I love a strong bass with music so it has to have a larger subwoofer. I am unsure if i should get matching satellites or if its smarter to have a stronger speakers infront with surround speakers that are smaller. I was thinking the klipsch quintet 2 or getting two klipsch floor standing speakers and their 12 subwoofer and adding the center and surrounds later. I haven't been able to find a decent audio place around here to listen to different set ups, although i am trying a new place about 45minutes away in hopes they will have better inventory. I'm open to any suggestions, different brands; really doesn't matter to me as long as they sound well.

Would it be a dumb idea to buy off of ebay new or used?

Can you also point me in the direction of a good brand, the only one on there I know is amazing is JBL; sadly that would be out of my price range. I have built some dinky speakers before that I'm currently using to hold me over until I find some nice speakers. Thanks.

What do you guys think about these?

They are more of a budget speakers but by klipsch, so I would figure they would sound pretty well. I would still need a receiver to power them, but then i could always slowly upgrade into a nicer system. But I'm at the moment more concerned with how these would sound.

What would be a good place to just buy drivers? I would assume i could get some nice drivers and build the boxes in my free time. I am debating whether or not to do this but I do like the idea of building the boxes myself. I have read up on the "how to," and think its easily done right. Is this a bad idea or good idea, I think is what I'm really asking. Thanks PDN for pointing out the low wattage on that subwoofer, I would definately need to replace that with a bigger subwoofer.

Just the items themselves, I wouldn't buy from either of those sellers. But that would put me right at budget after receiver, but I can not find anywhere to hear these Quintet III because they seem to be above Best buy and Circuit City, yet below every high end place around(which really has me worried).

Alright thanks everyone, I'm still debating what I'm going to do. I'm going to check out birch pricing and see if I can figure out a way to power these speakers if I make them since I will need a decent amount of power. Also need to research crossovers and decide if I want to try the ribbon tweeters. I somehow have a feeling I may end up with the rb-61s.
