Sorry for taking so long to get back to you but I have been away for a couple of days.
Grip is $25 and the bushings are $30. Not sure about the bushings as I have to admit to not liking the Venoms at all. I find them too dead for me and much prefer the Reflex.
Mate don't worry about not knowing about the beast there are only three in existence. check my page and look at the feedback jacko gave me on the photo of beast two. I have heaps of shots on there of the building process. Nice to think you mentioned drifting like a beast :)
