Bought one a few weeks ago also for $20, nothing like my coolsats for FTA no blind search, found it a little easier to use after putting factory files on it but still was sad and slow (my opinion) even for $20 i wish i had of left it where it was.
I got one for $45 on eBay, but couldn't get it to do anything.....wouldn't control my STAB HH100 motor, wouldn't blind scan, or autoscan for that matter. It was useless. I got a refund from the seller, and he told me not to bother returning it. It came with hack ware pre installed, but I installed the factory bin, which didn't help. Total junk in my opinion.
I have tried both the nova and the solaris and I have to say there is no difference between the 2 receivers except the colour. They both have a crappy GUI, no blind scan, and they overheat something fierce. I did get them for a good price (Free) but in my short time in this hobby I have to say that these boxes are the worst ones I have ever used. My first receiver was a VS Pro and its alright but nothing compares to my CS 5000 Platinum.. Hopefully Ill be getting my AZbox soon (Fingers crossed)
BTW, the Nfusion line of receivers were designed for the "Pirate" market with the guise of being able to access the internet for updates.
