I'm not sure about either of those. But, if you're looking to spend that kind of money, you could consider a cheaper Pignose one:

I've never used an amp yet, myself, but there is a group of folk musicians that play in my local area and the guy in the group who plays the harmonica told me that's what he uses and he'd recommend. The group's been playing for 10+ (15+, maybe?) years, so I'm guessing he knows what he's talking about...
