We have had this model for a few months & it darn near builds up no splatters and touts easy clean. Easy clean is well worth the small premium I feel.
I paid $170ish with PMing to Menards.com, but they're currently above HD's price so that's not an option.
Don't forget 11% HD rebate HD 11% rebate [homedepotrebates11percent.com]
if you're in an area that features 11% rebate match.
Can also pickup @ Menards w/ 11% rebate should you like them more and have Menards in your area.
