Depending on your budget. If the JDI's or J48 are beyond your budget, the Radial PRO series are pretty good too at a lower price. Can get those from Hung Bro's at Sim Lim Square. I'm using a Rolls DI too, not the best, but slightly cheaper. Going for the cheap and not too fussy about sound? Go for Behringer =P... DI-20, cost only about $40 for 2 channels. They are a little noisy I feel...
