Here’s one vote for the LP Americana caJon. I have one of the earlier versions and not only is it a good sounding cajon for the money, it is one of the best sounding cajons period. Highly recommend getting to a store and comparing cajons live if you can. Some of the more expensive ones I tried and some of the Meinls sounded a bit dead to my ears.
I have a basic Meinl cajon that cost $99. I tried out some more costly ones at GC, but could not hear much of a difference. I added a DW cable kick pedal to use it as a kick drum substitute for tiny stages; place a mic in the sound hole and it gives a good thump. I also bought a 3" x 12" barstool replacement cushion to raise me up when playing it as part of a compact kit (also helps for my sciatica).
