I have the Basic MistKing system, and will be installing it soon. I have been looking all over for the screen top wedge, and cannot find it for sale and in stock at any reputable dealer I know of for any less than $20+. That seems a little steep. If there is a reliable supplier OR a good DIY link, I'd be most appreciative! I am a new member but I already don't know what I would do without this community!
