Pretty good deal on the Diono Radian RXT. Looks like the only color combos are black plum and black scarlet, but a good price for a solid seat. Works from birth to booster, so could be the only seat you ever buy. (Still recommend an infant travel system for when they're little) I have one Radian 3 RXT, two Radian RXT and one Rainier myself. Love them all. Only real downside I've had is weight, and angle. Weight you can't really do much about, but its only an issue when we travel. Angle, we bought the angle adjuster and made a world of difference. I highly recommend it.
*Edit: The Shadow color is back in stock
