Easy to answer, since I just bought
this Ferndown and am eagerly awaiting its arrival. Like you, I've been acquiring briars for a long time, but had never acquired a decent quality bulldog. I recently browsed SP's estates on a lark, and this one just spoke to me. It's a bit out of your price range new, but as a 3* it's also quite large (0.90 chamber, 6.5"). So if you like the style, you might find a more reasonably sized 2* within your budget.
Bulldogs seem particularly interesting for this kind of question. Unlike most other shapes, they're defined primarily by a single feature (the bead) rather than a traditional set of proportions. With almost any other shape, I think you'd get a much more similar spread of examples than the wide variety of bulldogs everyone posted here. I've always admired the more fluid and graceful interpretations, and I think the Ferndown nails that. But I can see how others might prefer the flattened or extra-stout varieties instead.
