How much money on speaker cable?

_IMHO_
I second the JPS Labs cables. I was content to spend much less on cabling vs components, but, having heard excellent cables such as the JPS, changed my perspective. My cables are considerably more expensive than some of my components, but well worth the cost now in terms of sonic improvement.Once heard..its something you cant deny.

Don't buy into the thinking that you can get by with cables as an afterthought or some here think that because there's more length of wire in the components or speakers parts, that the last few feet of cable is less important..IMO, its THE most important last few feet that make it work or not!

IMO..

I too agree about the JPS Labs cables. They have worked magic in my system and have taken the sound to a whole new level. The JPS addition was really quite dramatic and I keep hearing more improvement every time a add another piece of their wire.

My suggestion once you have the system in place is to purchase used cables for reputable sellers here and experiment. It's fun and informative if you don't mind selling the cables that don;t work in your system.
After using countless cables ranging from inexpensive Canare 4S11 to super expensive Straightwire Blac Silc I keep going back to Audioquest solid conductor wires. After JPS labs, DH labs, Kimber, Analysis Plus, and others I have settled on the AQ Slate biwired and feel no need to look further. Not saying they are the cables for you but speaker cables do make a difference and the only way to know which is best for you is to listen.

I'll second and third reccomendations for Analysis Plus and DH Labs as good bang for the buck and appropriate for your system.

I've gone from $1,200 Nordost SPM Reference to $300 Pure Note Cerulean speaker cables to finance a PMC subwoofer purchase. There was very little sacrifice in sound quality in swapping cables but a huge jump in sonics in adding the subwoofer. I would agree with the idea of not spending too much on cables and focusing more on components. $250 would buy you a good decent cable that should do well in your system. The rule of thumb is to spend about 10%-15% the total cost of your system on cables(which include speaker cable and interconnects).
