Does anyone have suggestions for a high quality chiller (preferrably one that can be purchased with a limited budget)? I have an awesome powder diffractometer but it came with a Haskris chiller (closed loop) that's an absolute lemon. (My experience had always been that Haskris was the gold standard, but based on some things that I've heard and experienced recently, I've revised my opinion.) In the past year, it's caused the xrd to crash at least half-a-dozen times. (Okay, two were related to power outages, but that shouldn't kill a chiller.) We've rebuilt nearly everything in the chiller system but that hasn't seemd to work. We lost power again this weekend, and the chiller died again. We're thinking that we should invest in a new chiller at this point and would appreciate any advice that folks might have.
