MUST SACRIFICE CABLE QUALITY IN NEW HOME THEATER SETUP! but which one?

hi guys, Im setting up a new system at my new apartment. I have an infocus projector, toshiba hd dvd player and denon receiver. The thing is, if I put the projector, dvd player and receiver on same shelf, I'll have to get about 80 feet of speaker wires to run to a pair of loud speakers- which, also, would be only speakers i'll be running for this setup (I'm poor) The speakers are about 40 feet away from the equipment and have double set of inputs in the back. well, you guys know what im talking about better than I do... So, if i decide to put the receiver between the speakers, I'll have to get 3 pairs of 40feets of rca wires to run to the toshiba hd dvd player's dolbi outlet. Or, if i choose to put all the equipments away from the projector, I'll have to get 40 feet of HDMI cable for the player to the projector. See my dilema here guys? I've already heard that HDMI signals don't fare well in long distances and that's where the problem of clipping comes in. So as of now my choices are either get really long wires for my speakers or get really long cables for my receiver. And I can't afford anything grand. Infact, I'll only be able to afford cheapest kind of stuff. Or should I just go with the dts outlet on the dvd player this way i could get a nice quality cable of 40 feet? So which path should I take to minimize the performance loss? the path of least resistance, so to speak. heh heh. thx in advance
