I'm thinking of getting one but am undecided. I have a TSA right now but the shell is cracking around the feedneck and it is going to back to it's real owner sometime. The TSA has worked well so far but am interested in something new. What do you think of the 2KX loader? I like the fact that it only needs one 9v battery and is lower profile than some loaders. Or should I just spend twice as much and get a Halo B? The things that matter to me are durability, battery usuage and feed capability.
