We had Dinamap Compact T's which were an absolute disaster until they were all upgraded and have been fine since. The new ones certainly look nicer but are not really easy to work with. We started to buy Datascope Accutors now but we have real problems with the batteries which lead Datascope to supply us with free batteries for 3 years cause they reckon a lead acid battery won't last much more than 6 months. In my experience best avoided.
