I was not aware that MJmods were gone. I wonder if Hydro Korola helped put them out of business. The cost of the kit, mag mount, and the pump itself amounted a bit high. I have two MJMods and finally like them. I say finally because it took me forever to get the prop from turning in reverse. Also, finally bought some affordable magnets to make them mag mount. I'm interested in knowing what else is out there. I think I'll tag along.
