Topcon CT14non-contact tonometer

I am looking to purchase a tonometer to monitor my ntg pressures and have the possibility of purchasing a TopconCT14 non-contact tonometer (used) through my behavioural optometrist who is upgrading her equipment. Could I have some feedback if this might be a good tonometer for me to work with? I have looked through the fiteyes topics and can't seem to find any evaluations by Dave or others concerning this tonometer. I am eager to get started on the journey of understanding my individual pressure cycles and using the info to develop a healthier lifestyle. 

Thanks folks
