mp10qd on mobius, not sure how old it is i bought it on here about a year ago, it works good but makes noise at higher rpms, was quiet but my cat knocked it off the tank about 8 months ago and it started making noise, ecotech said send it in and they would look at it and give me some options but i decided its working so its not that big a deal, wet side is soaking and will be cleaned before its shipped, anyways id take $175 shipped, paypal only, text for more info 251-472-5002
