Cable Company reps seem very hit or miss (sounds like maybe you got the latter), and some here have latched on to one person they trust and are knowledgeable. That said there are several direct sellers who offer low-risk trial periods, and in your price range I’d recommend checking out Snake River Audio as they’re in your price range, get very positive reviews from users, and they offer a 30-day trial period less return shipping and credit card fees. At least worth a call I think, and best of luck.
