I wish I could get any rebates. Not even for giving some lessons at the Uni In the Service of the hospital where I made the residency they had their own camera with a good macro lens and ring flash. Everyone could use it when needed, and the hospital payed for the slides film developing.
In this hospital they had a medical photographer years ago, but the man retired and they didn't hire a substitute. Anything you want for pics is on your own. They used to provide the Ektachrome film, but didn't pay the developing. Fortunately they provide the endoscopic surgery cameras and digital recording systems, but it took a lot of effort and negotiation getting the last.
I'd need to have a different tax status to be able to get rebates from these purchases. My almost none private practice and the rebates won't justify the extra charges and hassle.
