Just got one 2 weeks ago for $287 with discount. Loved the quality and looks of the T-Bag Roller Dekker as they stand by their product according to their testimonial readings. Will try it out for the first time we go on a trip over Memorial Day weekend.
Check out ebay, as you'll likely save another $20-$30 there. Eastern Perforrmance sells them on ebay, good Company to deal with etc. That's where I'll be buying my back seat T-Bag from.
