I believe I listed a few specific models. Any one of them should bring you in well under budget. You may want to consider another resource. For cables, I use The Cable Company. They have a demo program where they lend you a bunch of cables that you want to try so you can demo them in your system. I use them all the time, as do many other people on this site.
If you just need something to get you buy and don't mind taking a small chance, find a good used pair of AQ Jaguar. You shouldn't have any problem finding them in the $100-$200 range. Its a true high end cable that sounds very good with just about anything. You can use it as a reference for judging other cables and you'll always be able to sell it for about what you paid. I have a pair of TARA The 2 that went for about $1500 and they sound just as good. Even a little better in the bass.
Like I said before, you have really good, well matched components. You don't have to play the cable game.
