Someone in another thread provided a link to an APC S10 for only $200 shipped. That's an incredible price, so I pulled the trigger. I just received it yesterday, so I thought I would post a small review. http://search.vanns.com/sitesearch/search?q=apc+s10 First, it appears to have lots of high-end features for the price. I think this must be a price mistake, because it is $500+ everywhere else. Even at Vann's the black version of this same model is $600. I looked up an estimate of the shipping and UPS puts it around $85 to ship. I don't know how they are making any money off this. Anyway, it's big and heavy. It is quiet during operation until you pull the plug and go battery. On battery power the fan is loud. It can be rack-mounted and even includes the rack mounting hardware. It came with a power cable, a couple of coax cables, and a network or telephone cable. It has a lot of bells and whistles designed more for home theater enthusiasts, but these won't get in the way of computer users. These might be a bonus for you if you are working on high-end audio on your MP. This thing has quite a bit of information available in the display. While the display can be turned off, the power light is one of those super bright blue LEDs that can light up the whole room at night. Kind of annoying. I would say the only down side is that it is quite large. The only way I can fit it is on its side. I can't find any warnings about the orientation and the box doesn't say "this side up" so I assume the battery is a sealed unit and being on its side is fine. Also, it was on its side on my porch for who knows how long when it was delivered. Only one day of use so far. Overall I'm happy with it. For the price I paid, I'm ecstatic!
