Preferred rectal speculum/ scope?

I was thinking of investing in a new rectal speculum or scope and was wondering whether people here had preferences. Right now I have a Hirschman Anoscope, but I find that the edges can feel a bit uncomfortable as it goes in. I was thinking of getting a two or three pronged speculum, but I've read that they can often pinch. Thoughts?

I have good experience with this: https://www.medtech3000.de/-Rektoskop-Proktoskop-Set-4-Stueck::99.html They sell a handle and insertable penlight separately. I know, it's plastic. But at least it goes in smoothly.

I also have an anal speculum, but it scared the living daylights out of me when it got stuck inside of me (I did get it unstuck myself). If sharp edges are a concern to you, don't buy something with lots more sharp edges?
