With that sort of length you should get some heavier gauge speaker wires. I would go for 12 gauge. Look on eBay for Mil Spec silver plated Teflon insulated wire. I bought a spool of 12 gauge 600 feet (more like 700 ft really) for $40 last Summer. It makes great speaker wire.
I twisted a quad foursome, and wrapped it with Teflon gas-pipe tape... it took a lot of work to do 100 ft long, but it is nice.
If you want a 'real' speaker cable, I would go for Kimber 12TC for your fronts. Then 8TC for the rears. The total cost would be in your price bracket.
Good luck. (I like your choice of equipment!)
