Cheap DI box with 2 inputs > 1 out?
 

Anyone know of a DI box, cheaper than Radial's JDI, that has 2 inputs which can be merged into one output?

Would like a JDI but it's over my budget.

I've read that the Rolls DB25B can possibly do this but haven't found any real confirmation, also, anyone know if the 1/4" and XLR inputs on the Behringer DI100 can be used simultaneously?

I suppose I could just get a passive mixer (both sources are low impedance) and link that to a DI, but it'd be nice to have it all in one box.

EDIT: I've been told the DI100 has 3 inputs (XLR, input and link) that are wired in parallel, meaning I should be able to use them all. Sounds like what I'm after, but any other suggestions welcome :)
