Any opinion on FatCongas cajons?
A buddy of mine has one ... and I'm not crazy about them, but they are decent.
As far as the prices, you need to ask for a better price. Also keep in mind that this is an import. You're not going to be able to buy it from Schlagwerk for the price you see on their website.
In my opinion, Schlagwerk makes the best cajons!
I have a custom cajon made by a man who also makes taiko drums. If you are interested, I could pass along his info to you. He only makes about 50 cajons a year now ... but they are beautiful and sound great. It all depends on what you are looking for.
