I haven't checked the US prices on the Q grills, but I know that Weber has implemented price hikes pretty much across the board. WIth the way things are going, I won't be surprised to see another increase by summer.
Should help with rehabs, but I have seen too many sales on the little Q1xxx grills that were as low as $159 US brand new. That made it pretty tough to eek out any profit on a rehab. I didn't pay much attention this past summer and supply could have been an issue, but I don't remember seeing the steep sale prices on them. I have a couple I would like to clean up/fix up and flip. Maybe this next summer?
