Analog film photography and cameras

Right, does anyone know anywhere that does slide/neg scanning at a reasonable standard for a reasonable price?

Reason: the slides I had scanned came out looking like turd. I was gutted. 3 months of photos and most of them are shit. Until I projected them and most of them are fine/what I was hoping for.
Weirdly though, the colour neg stuff is totally fine/the scans are actually pretty good. This leads me to believe that the scanner was just set up wrong/badly.
Frustrating it is. . .

Slide/tranny has a MUCH higher DMax than Colour Neg - hence why your scanner struggles...
