The price is definitely more affordable for the MV50, but keep in mind it does use inferior components when compared to a VIAIR unit. When something is cheaper like that, something, it has to use cheaper materials. A lot of people compare to the VIAIR, and although it look similar, it is very different.
The piston seal is not made of quality material like teflon, the bearing are cheaper, and the valve inside is not stainless steel. So, over time, it will not hold up to its performance.
Sorry for the rant.... you can always find threads where people are disappointed with that compressor. On the other hand, we do offer an economy OBA system for $299 if you wanted to go that route and have the option for air tools and air locker activation if you have them.
