I'd like to chime in about Behringer, I have one of their 412 guitar cabs (with whatever stock Jensens they load it with) and despite whatever I've thrown at it (a fair portion being questionable) I haven't had any problems. Before I got my Sunn 412 for my Coliseum Lead I was using the Behringer and an Ampeg 410 bass cab that gave a pretty good "odd" sound. On a budget I think it's a safe bet.
I agree with you, although you must admit it's pretty hard to screw up a sealed, Jensen loaded 4X12 guitar cab. I wasn't trying to slight Behringer, but I was serious when I wrote "IMO Behringer makes "questionable" gear at best, but it's cheap enough to throw away when it breaks and buy another one!" It is what it is, kinda like a Kia or a Daewoo in the car world. It's all relative, questionable quality but very inexpensive can still be a good value overall.
I wouldn't hesitate to buy the Behringer DI for $40, you could maybe save a few bucks and build a reasonable working DI for the application discussed way back when in the beginning of this thread, but you couldn't build
this for $40 unless you steal the parts from an electrical supply house;
