A guy on this site that has a national following. His name is John Mraz and his user name is Gibblet. He's Bucknasty on www.archerytalk.com and his business is known as Bucknasty strings. I've had very good luck with them. Comparable to Winner's Choice in quality of workmanship using the same string materials. Cost is about 2/3 that of WC's. You get to be creative and pick your own colors, too.

On AT there are sponsors that make strings also. Many of them. There's Prostrings, Vaportrail, H&M, and so many others. I feel fairly certain that once you pick one and try their strings you'll stay with them. If the product is what you pay for there is no real reason to keep getting others. Afterall, you don't buy a set every week just to compare them.
