The major differences between RIS 1.5 and 2.0 are the RIS software and the IR Tower. The software upgrade from RIS 1.5 to 2.0 is $19.99 (#3805) from LEGO's website. A USB IR Tower can be purchased from pldstore.com (W979783) for $29.00. There was no (...) (23 years ago, 16-Dec-02, to lugnet.robotics)

Currently debating in my head whether of these versions is the best to buy. I've checked the inventory with Peeron, all RIS kits appear more or less identical in their supply of parts.
