Quick speaker question

[FCdrifter]

Hey guys, I'm planning on upgrading my existing home theater system and have been doing some research around here and have already chosen a receiver, but my current system is basically a home theater in a box so all the wiring is spring clip wiring so I need to buy a new sub and I'm assuming new speakers as well. I've chosen the Sony DG820 for my receiver which has screw type fasteners and I'm assuming spring clip wiring isn't going to work here, at least for the sub. My question is are their any relatively cheap speaker systems that include all speakers and a sub that don't use spring clip wiring? I'd like to buy all at once to save cash and hastle I guess, but if I have to buy seperate I was looking at a cheapie Sony SAW2500 sub I think it was, but as for speakers I don't really know where to start. I'd like a complete set, at least a complete set of speakers in one box would be easiest, but any advice you could give would be great.
Thanks
