I bought a very cheap German one for that particular job...75-100 dollar
it worked okay !!!
I gues it took me about a good 40 hours to do all the puzzle-like cutting with it.
Do buy a bundle of thin blades...the break very easy ;)
If you want to go that way pay attention that you use different panels in thickness and wood...in order not to create a dominant resonance.
The panels I glued together (with a variation of soft and hard compound to glue with) varied in 12-22 mm thickness and I used e.g. Beech, Multiplex, Merantie, "Spaanderplaat", "Softwood" and sheets of Lead in between.
Beware in the end the Mid can only be lifted safely by 2-men.:eyebrows:
