My personal experience with the Vxi Talkpro Xpress is quite good. I can also add my $.02 worth to praising Martin Markoe. I have bought several mics from him over the years and have always been impressed with his knowledge and with the service of his company. "A fair deal for a fair price" is how I would describe eMicrophones.com (And no, I'm not a wholly owned subsidiary, nor do I have any relationship with Martin other than as a satisfied customer).
