What is the best breed of babble fish to buy?

I heard about the intergalactic highway that's gonna be built in 2012, and I need to get off this planet, FAST. I'm hitchin a ride with Zaphod on the Heart of Gold, but am still unsure on which brand of babble fish to buy. I heard they're all different, and I want one that won't bee too itchy or too loud. Help?
