What Should I Look for in a Long Range Wifi Adapter?

[Bmoe]

I'm looking to get a wifi adapter for a mag254 I ordered. I am going to need one with a good range because I plan on moving to a bigger location and may possibly have two floors. Need something that if my router was on the first floor (and assuming the router has a good wifi signal range), then my mag254 wifi adapter on the 2nd floor would be able to pick up the connection and stream fine. I know this is possible as my dad in law has a router locked inside a cabinet in the basement and I still got good signal on the main floor.

I find this better to use,

Plug it in behind the tv you will never see it.
Plus has great wifi on it but you can plug your mag into it like i do...connection never lost.

I totally forgot that I'll have an extra router which has a repeater built-in. This extra router is my main one now. It was fairly cheap when I bought it ($10) and the range isn't all too good (has trouble penetrating walls). But when in range it does a pretty good job. I might just get an extender to use with both of the routers if the routers by themselves aren't good enough. I don't plan on running ethernet into an extender though. That being said, if my range extender is good then I guess my wifi adapter for the mag254 doesn't need a whole lot of range. The entire place I plan on moving too has square footage ranging from 1500-1900 spread among two floors so hopefully if I have to buy anything, I can get it for under $20.

Where could one purchase nanosat? I googled the term and saw pictures but not an official manufacturer. If they are significantly that good I wouldn't mind spending a little extra.
