I researched this hammer pretty extensively. I spoke with large repair shops, different OEM reps and came to the universal conclusion that even opposing hammer makes, had nothing negative to say about the hammer itself. One repair shop stated that have had issues getting parts at times, but honestly I suspect that could apply to everyone.
I was traveling to ND from Idaho and as I often do, I stop some of the dealerships on the way. I was in Billings and stopped at Titan. I saw this hammer on their website prior. I found and bought a new 2' bucket for a 160 that they had (half price of current new). I asked about this hammer, they showed it to me and it was demoed once but near new (I later found out by another salesman that was used to demo a pool and that was it). I started the negotiation process and bought it coming back from ND a week later. A new MB1000 was quoted to me at $37500 out of SLC. I got this one at 28K. I haven't hooked it up yet. Waiting on the owners manual to show up. I need to square away the auto lube. I bought it to primarily break lava rock.
I had also heard good thing about TOKU from a repair shop who quoted me a new one. Having auto lube installed already was a big deal for me. I hope it works as advertised. Makes great sense to me.
