Your opinion of Rocks TV?

I registered on the phone the other day, like I need another jewelry channel to spend money on, this makes six or seven. They seem a lot like Liquidation Channel in their offerings, cheaper stuff. How is the quality for the price? The guy that took my info was beyond polite and informative, my Anglophile girlfriend would have been impressed with him. The hosts all have GIA training, but are a bit unrestrained in their selling tactics. The only thing that really bothers me about them is their absolutely horrible manicures, the worst on TV.
