Tenpoint, Ravin or Excalibur. I'm a fan of Tenpoint personally, I like the company and warranty. Ravin are also fine, just not my cup of tea, many are happy with them though. Excalibut are probably the simplest and need the least maintenance but only offered in traditional limb design. check them all out, shoot them if you can ( many shops will let you demo one) and buy the one you like best.
