I have a Z7+ and I'd recommend staying away until they fix their issues. They charge a premium for the box but it's full of bugs and issues. The EPG doesn't load properly, the box won't come out of standby if left for a day, connects to my wifi very slowly, sometimes it takes a few tries to turn it on, etc.
They're releasing a new firmware this month so we'll what's fixed but until it's running properly I'd stay away.
Where you located? I have a guy who's generally cheaper than the stores. He doesn't ship though.
Get a buzz xpl 3000, i had lots of problems with warranty from them
if you are in the GTA, try wintronics. its a store has a few locations arround. they ship too i think. google them
If you mean the Z7+, you can Dreamlink.ca. I believe you have to email them for pricing and billing. Amazon is also an option. Ebay. Most Vader resellers offer them as well. I got mine from a guy in Facebook called Kargul Bacon who runs a page called We The North Vader Streams. Good price, fast shipping.
