Does anyone know an e-mail address for Hi Grade Productions?
The one on the links page has given no response and after doing a search for it , it actually turns out to be something to do with a religius-cult survivors self-help type-thing.

Also of concern is that in checking the p.o box number I've found that it is registered to 'turf research'.

Is Hi Grade genuine?

The postal address given here was correct the last time I used them, over two years ago, and they had given me reliable service over several prior years.
Whether they're still on the go, I have no idea.
I suggest you write, and see if a catalogue results- then you'll know for sure.
