After reading reviews, I'm about to pull the trigger and buy a Marpac white noise machine from amazon. But there are two versions that both have good reviews.

There's the original and a smaller "travel" version. http://www.amazon.com/gp/product/B002GTR902/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A2U3XBAMXKHMHK

Anyone have an experience with both or with the travel one? They are the same price, but I'm thinking smaller would be better in general (and the reviews say the sound is as loud or louder than the original). But maybe the original is better for some reason?

Any advice would be great!
