I use a Silva Trail. Used to have an Alpkit Gamma but when it died they were out of stock (these things sell fast).
The Silva is definitely brighter and a bit more refined but it costs more and lacks the over-the-head strap and tail light. Still a good torch though.
As an aside, no tail light might be a good thing. I used to stop for a pee, switch off the head light and think nobody could see me in the bushes ... forgetting I had a flashing red light on the back of my head ...
Sounds to me like you're getting a good service. Regular checks and the promise (or threat!) of action when and if your symptoms become serious. I'm not sure what they're supposed to do if you're not in distress or the condition hasn't developed.
You can turn to Dr Web as Faithsdaddy advises if you want .... good luck with that if you do.
