I'd say £800 a year is a lot less than going on a paid stalk every month. Provided of course, there are enough deer on the land. But I think land owners need to realise that this effectively turns you from being someone who owes the farmer a dollop of respect and favour into a customer.
In general I have to say personally I don't like the idea of paying for shoots and prefer to provide general pest control. I have 5 main farms and several other small shoots, none of which I pay for or ever intend to. Two have good roe numbers and I've been told to help myself, and fully intend to once I get my variation back!
These shoots I obtained initially to control rabbits, and sometimes woodies as I have a good reputation as a reliable, trustworthy chap with local landowners. This has taken a lot of hard work, and there is no doubt I'd never have got these just for stalking rights (quite apart from the fact I don't have a deer rifle on my FAC yet!). I'd prefer to earn trust and respect from a farmer for effectively controlling pests each and every week and therefore be granted the right to take deer, than pay for the privilege.
A few farmers around my way now charge for woody and rabbit shooting. IMO this is a greedy p*ss take and seems to be on the increase. Paying for deer is one thing, but it does seem to have a trickle down effect on rough shooting too.
I spend money on a shooting vehicle, diesel, ammo, rifles, clothing, etc etc every month and the farmer gets an excellent pest control service saving him or her thousands a year. I don't expect payment or thanks - I do it for the love of it and for free meat in the freezer. On the other hand I don't expect to pay for it!
I know of a couple of famers now who have lost their regular, reliable lads as a result of turning to charging for rights just for general vermin. The day a farmer asked me for money to shoot bunnies would be the last day he saw me.
