Best overall would be the 1/35 scale kit from Trumpeter, but it is large and expensive.
The Monogram kit in 1/48 is old and out-of-production, but can still build up into a respectable representation of the Hind. There's also a bunch of resin upgrades tooled for it by Cobra Company (see the other recent thread here). The kit routinely pops up on ebay and in model trader forums.
Those are my recommendations. Supposedly, there is a Trumpeter 1/48 Hind-F, but I've never seen it, and I don't know much about 1/72 because I don't build in that scale.
