�100-150 Any Newbery 5 star. Any model, but my favorite is the Mjolnir.
Any Hell for Leather Devil. Just because!
�150-200 Warsop Platinum. Go see Tony and Claire, get a custom made Warsop, Grade 1, and you get to see the lovely Essex countryside. What's not to like.
�200-300 Hell for Leather Pro grade. I recently visited Matt @H4L and saw a few Pro grade bats. I got wood! Light clefts, serious amounts of wood where it's needed, and branding of the first order.
>300 I've only seen one, but I would put my arm up for Gary @ Choice. The Pretorian. To get Gary to spend time with you discussing your bat AND to get the best of his willow stash, well, that's worth a few beers to celebrate.
Hope that is (at best) an interesting answer.
