I presume you are interested in the far less expensive Stand By UPS's and not the far more expensive On-Line UPS's. Since there is no evidence that the any of Dish's STB's are Energystar 5.0 compliant (nor complaint with ANY Energystar version) just about any standby (the least expensive UPS's) UPS should do the trick for a Dish box. APC is very popular. However, be aware that for many of the latest PCs, AVR's, HDTV's, etc. that are Energystar 5.0 compliant, you should consider at least something like the lower cost PFC Sinewave Stand By Series UPS by CyberPower or even better (but more expensive) one of the Smart UPS line of APC UPS's, but I believe APC only offers it's Smart line as On-line UPS only, hence the higher retail price.
