For solid surface it is very depend on the material. You cant compare just like this because local/china made solid surface is durable if compare with LG which cost rm200++ depending the color and the design you need.

Note: LG provides 10 yrs warranty on the stein. 

If you want to compare the price, you should compare other material, for eg melamie, 3g other than solid surface unless you know they are same brand.
