If your interested in a cable descrambler you should first Know that they do not work on digital cable.You must have analog cable meaning your channels do not go over channel 125,everything over 125 is digital cable.All universal cable descramblers work the same if one will work for you then all will work for you.You should never have to pay more than $169.00 for a cable descrambler that is unless you buy a tristar mx which can cost up to $299.00.Here is 2 sites i"ve ordered from and had good luck with and they have good prices.www.2005cabledescramblers.com and www.descramblers4u.com both also have great wholesale prices and ship cod if thats what you want it may cost $10 more not sure but the prices are definately worth looking at.I bought 10 for $89ea
