If you are primarily concerned about a return policy, I think it would be easier to purchase from a store on the WWW rather thab trying to eliminate manufacturers. An example of an on-line store with a return policy is Audio Advisor (http://www.audioadvisor.com/). Quite a few other online stores have return policies.
You also might try to buy from a manufacturer who sells direct. An example is Decware (http://www.decware.com/newsite/homepage.html).
Whatever you do, speak to someone at the store/manufacturer about their return policy. Some have rather hefty restocking charges.
Of course, the disadvantage is you can't hear first unless you don't mind or car ride or you choose a seller close by.
