Receiver are one item I'm very particular about. If I don't run a receiver made by the manufacturer, I fly Bergs. Never had an issue with a Berg. I've heard quite a few stories about the cheap Chinese knock-off receivers to the point I don't think I'd want to try one. I just received an order today from Tower which included (2) Berg Micro-Stamp 4L receivers @ $24.99 each, and crystals @ $6.79 each.
