Personally I would avoid Peaktech for any instrument: they are only rebranded and overpriced items without any single added value. You can get the same from the original manufacturer for less price.
Also, their support was quite useless to me: I asked them why I should choose their PSUs instead Manson's: since they are the same units I asked only if they request to Manson different components for their units or if there is any difference between them but they felt literally offended by my request and quit the conversation.
For me, Peaktech is "don't touch it even with a 6ft. pole."
