Don't touch Roger Buss with a bargepole - he'll fleece you for your money and you probably won't see a thing. If you do I'll bet the trophy fees will cripple you .
Many people have been taken in by this plausible 'gentleman', usually newcomers who end up paying a fortune and not seeing or shooting anything!
The only people I have recently had experience with are Jelen Deer Services, who I can recommend. Don't know if they can help you or not, try http://www.jelendeer.com/
I've got be honest and say that I have stalked with Roger Buss off and on since 1989. He is certainly not the most honest of people and I can easily see why people have a problem with him but I learned how to manage him and learnt lessons as I went along. Foremost amongst these was to agree and confirm the stalking fees prior to the outing.
Money issues aside I have had few problems with him.
In terms of the quality of his ground I can only say that I saw deer on almost every outing with him over the years and had a chance to shoot a beast on the majority of occasions. I have visited his ground in Hampshire, Wiltshire, Sussex, Gloucestershire and Herefordshire. There were one or two pieces of ground on which deer numbers were low and I just refused future outings on these sites. I have personally taken good fallow and roe from his ground and seen medal animals of both species.
He's not my favourite stalker and I feel the need to be on my guard financially but I have never felt like dropping him and have been quite happy with the stalking.
