Memory foam - is this a good deal?

[AdamMontana]

I have a hard time believing the overstock hype of "$3150 reduced to $350!!!!!!"

http://www.overstock.com/Home-Garden/Accu-Gold-13-inch-5.3-Queen-size-Memory-Foam-RV-Bed-Sleep-System/4047669/product.html?cpncode=23-51226160-2&srccode=cii_10043468&cid=128247&fp=F

Can anyone give me advice on purchasing a tempurpedic / memory foam / latex bed?

Thanks!
