I've o experience of Lekka, but Woodstock and Hammer are red herrings.
For that money you can go fully custom and have more say about the cleft and how the bat should fit you, and not the other way around.
Not saying the retailers here can't do that. I know first hand that Paul @IJC offers excellent service and hand picks bats. I've no direct experience of the other retailers but their reviews are worth reading for piece of mind.
Keep your money tucked away until you've spoken to Paul Aldred, Matt @H4L (two whom I have used and would recommend all the time) and the other makers who gain great reviews.
Choice! You've never had it so good. Confused? Of course, we all are (in varying ways and levels).
Have fun and make it an enjoyable process.
