Hemachron 100 vs. iSTAT and HMS

Hello. We are looking at bringing in the Hemachron 100 and are looking for some pros and cons on the device. We currently utilize the iSTAT ACTk and HMS. Anyone else transition from iSTAT and HMS to Hemochron? How do you feel results compare? In your experience, does it seem to be more accurate than the other devices or less accurate? We have noticed with our iSTAT and HMS, we have an incredibly hard time getting them to correlate at high concentrations of Heparin. Anything you can share would be greatly appreciated.
