Most international releases are USBC approved (and PBA registered if the rest of the brand is), the only thing is getting your hands on one.
Billy, if you're keen on DT then you should check out 900 Global and AMF. The guys behind DT are there now, the new DT is unrelated to the DT of last year. If you like Ebonite, try the new DT. If you like the old DT, go with 900G/AMF.
