[QUOTE=walkerblackwell;12758]I suggest the i1Pro2 or used DTP70. These are both great spectros and PiezoDN supports them.
On cheaper side, a used i1Pro1 can be very cost effective. Just don’t buy a RevA version get RevB or RevC or higher if going with i1Pro1.
Walker - thanks - good to know about the revision letters on the i1Pro units.
