That sounds like a good deal. I bought two of the Sunshine Radian XTSL and paid about $260 for them (got them on Target.com with a 15% off coupon code but that was back in January). We haven't installed them yet but we tried them out one day in the car and they seem fantastic (and easily fit two radians plus my Graco Snugride).
Re: Sunshine Radians-any sales on them?
I was just looking at these yesterday. This was the cheapest place I found online $184:

The warehouse is in West Haven, and you could pick them up if you needed to. I wonder if they would cut you a break if they didn't need to ship them??
