I went to Circuit City to buy a Slingbox Solo and a 1 port SlingLink Turbo. I was shocked oto see that the SlingLink was tagged at $40.96 on the shelf, this normally retails for $99.99. I grabbed 2, I figured for that price I might use the other one in the future. I took them to the register and the cashier scanned them, they came up at $79.99. I told the cashier the tag read $40.96, she replied to bring the tag up to her. So I went back to the shelf and grabbed the tag, to my astonishment $40.96 was for the 4 port SlingLink Turbo. I grabbed the one remaining 4 port and headed up to the cashier. Sure enough it rang up correctly, I was on my way home with the $149 device for $40.96.
I have since set up my Slingbox Solo and the SlingLink Turbo and I can't recommend both pieces of hardware enough.
I checked Circuit City's web site and this model is not on there. So this is YMMV if you are lucky enough to find one still sitting on the shelf at Circuit City. I had to dig back on the shelf behind the 1 port models to find it.
