The Omron STI OptoShield OS3100 is very similar in form and specifications to the various SICK "coffee-pot" laser rangefinders, such as the SICK LMS 291.  Due to my lack of familiarity with this particular laser rangefinder, I have no indication of cost; however, it appears to have a 25 Hz scan rate over 180° range, with 0.36° angular resolution.  The sensing range is 4 meters (at 10% reflectivity, max range of 15 meters), with an error of about 62mm.  Again, this is a "coffee pot" reader with a rugged metal housing, making it rather bulky (15.5 x 17.7 x 15.6 cm), weighing in at approximately 4.35kg.  They require approximately 20 Watts of power, operating off on a 24VDC supply.

A detailed specification sheet can be found here.  The blog post containing a disassembly of the OS3100 may also be of interest (see photos below).
