I recently bought the RA Bock 3.2V Bright White LED Otoscope Set for my personal use at home.  It uses C batteries which is great if you have rechargeables.  I have used it a handful of times and the weight and reliability are on par with much more expensive Welch Allyn versions. With 4/5 star rating, this set is affordable for the home at just under $100.  Click the link above or just click HERE to start your Amazon shopping to help support the show!
