from what i understood they were clearance items. i bought one at the store for 99$ and 2 30$ mail in rebates. it's a tripp lite and works great. handles my 300w pc and 21" monitor for a few minutes, great for just shutting down. just dont expect it to run for very long. tripp lite has excellent customer support btw (ibm just slaps their name on it, tripp lite does all the service).
