Which baby thermometer brand/model is the most accurate?

I have a Braun Thermoscan 5, which is serving me well. I bought it for $66 off Carousell brand new, but I'm pretty sure it costs cheaper on Amazon or something. Many medical institutions, hospitals and GP clinics use Braun, albeit the higher end and professional models, but I think the models meant for home use work just as well. The readings are accurate and it only takes a few seconds to get a reading. I highly recommend it. There's a newer model, Thermoscan 7 as well! http://www.amazon.com/Braun-Thermoscan-5-Ear-Thermometer/dp/B00PINP5BI/ref=sr_1_2_s_it?s=hpc&ie=UTF8&qid=1459591917&sr=1-2&keywords=thermoscan+5
