You have to draw a distinction between what is active and passive somewhere. The Schoeps Colette cables are true active cables, with active circuitry in them eliminating the need for bodies. Unfortunately, the only preamp that I am aware of that can supply power to them is the VMS5U. It is a fine-sounding preamp, but very expensive, making the entire setup outside of your price range. If you want to use them with another preamp, I believe that you need the CMC bodies.
The Neumann KM140 has active capsules and the MBHO 603a have active preamplifiers allowing each of them to have a remote placement of the body and capsule. You still need both the body and the capsules with these, so the cables essentially function as extension cords. The dpa 4022 and 4023 microphones have miniature bodies (they are not bodyless), making the entire assembly like 1 inch long, while the Schoeps CCM series are bodyless microphones and are about the same size, if not slightly larger.
If you are truly wedded to a setup that allows for bodyless microphones or remote placement of the capsules in your price range, the AKG Blueline series is the only thing to my knowledge that would work. It uses extension cables for remote placement of the capsule. For the same amount of money (or a little bit more), however, you can probably pick up a used set of the 480 series that sound better, IMHO, but do not allow for remote capsule placement. Or you can go for a used set of the dpa 4061 microphones that sound better than the AKG Bluelines, IMHO, and are very small.
