We present the most interesting results from our survey of eclipsing binaries from the All-Sky Automated Survey (ASAS) catalog. Radial velocities were calculated from high-resolution spectra obtained with Keck I/HIRES, Radcliffe/GIRAFFE and AAT/UCLES telescopes/spectrographs. A novel iodine cell technique for double-lined binaries was also involved. Photometry was taken directly from the ASAS or from dedicated observations at the Elizabeth telescope (SAAO) and fully-automated PROMPT facility.For a sample of systems we derived very precise absolute values of fundamental parameters. In our sample we found 6 new low-mass systems, 4 pre-main-sequence candidates, and several other binaries interesting from the evolutionary point of view.
