Depends on what you consider to be reasonably priced. I'm using a Running Springs Audio Haley, which I was fortunate enough to buy as a demo. There are many out there. Some others that come to mind that I considered are APS, BPT, Richard Gray, PS Audio, and Exact Power. A lot of people seem to like the Shunyata products. What you'll find is that there are many philosophies to power conditioning. This includes active (such as balanced power and power regeneration) and passive (such as filtering) approaches. Many will claim to be non-current limiting and non-coloring. Only your ears will tell if their claims are true.
