V&H are good pipes deep tone and have a generally higher price of the ones you've listed.
The wild pigs are excellent pipes and at the price of $150 or less on ebay you can't go wrong, they have three baffles, get the smallest if you're stage 1
www.wildpigpipes.com they sell seconds or overstock on ebay and everyone I've heard from loves them
beats $400 for a set of slip ons.
www.khromewerks.com makes a good set of slip ons as well has a special baffling system.
For the money I'd go wild pig.
