Why not an Iron Monster? There are many bargains on used 15" import planers, depending on your location. I found a Powermatic Model 15 for $454.
I doubt the table-top DeWalt will last long planing 12" widths. But, a well adjusted cast iron 15" will gobble up wide widths. Look for Delta, Grizzy, Jet, Powermatic, or Shop Fox 15" planers. Just my .02....
