We have the DXH800's with the SMSS. Service is good. The Stainer does require weekly (almost bi-weekly, if you have a high through-put) maintenance but it is fairly easy. We had to play with our stain a lot before we got it right. Our pathologists were very picky. I would not recommend the BC buffer. We used Volu-solv buffer with great results for smears, bone marrows and body fluids. I have heard good things about the DXH900 from other places. We will be looking at that one next, mainly for the Sepsis Protocol. Does Sysmex offer a Sepsis Protocol?
