Ermmm, not me...yet! I've got my own beater to practice one and I keep on finding reasons not to do it 😁 I' ve got to take off the top, replace & glue in all the rotten bracing and then pop the top back on. Never done it before, so I'm more than a little nervous.
If in Cpt, I can recommend Traut Guitar Worx, they're really reasonably priced. Though I suspect the top would have to be taken off to do the job properly, hence the high quote (also you never know what else lurks beneath).
