I want a cajon

these things are so versatile, it's amazing. I have tried out quite a few and I like the fat congas string cajon the best overall...

Fat Congas String Cajon Drumthis thing has double the bass of anything else I have tried, including all the various meinls, which are pretty but lacking in bass. it also has an option of a non-string sound, more like a trad cajon.
I liked the mountain rhythm models I tried, believe it or not. very great string sound. a little lacking in cosmetics and perhaps build quality...
the lp models sounded ok, nothing special.
I tried the schlagwerks peru model. very similar to the meinl, I thought. but pricier.
the only trouble is the fat conga is so expensive, about double the others mentioned. obviously they know they have a great product, I guess...

still it doesnt look like anything much....
anyone have experience w fat congas? cajons in general? advice?
