Your question is tough to answer. The unofficial "workhorse" category normally consists of multi-pattern condensers with a new street price that exceeds your budget. (a lot of inexpensive truly mobile recording rigs may have a hard time powering these honkin' mics, too, it's worth mentioning) Do you have a long time frame for the purchase and are you willing to buy used? Or do you want to go buy it new off the shelf now with warranty/support? If the former, you can educate yourself about a number of different mics that would work, and then hunt/gather/hide/stalk out a good deal on one that would cost a lot more if you bought it new, staying inside your budget. If the latter, then you might want to start saving, and possibly think about a compromise to tide you over in the meantime.
In my case, I have a laptop and a bus-powered interface, and I scored an AKG C414B-ULS for less than your budget, but the downside is that I still need a power outlet (for a dedicated phantom power supply), because the interface doesn't provide enough phantom power juice to properly operate the mic.
