I've been trying to decide between the Dewalt 735 & the Delta 22-580 for some time now and with the deal that Lowes has right now I think I'm finally decided on the Dewalt. BUT, most of the time when I get wood for a project its rough-sawn and for some reason I gravitate toward the super hard exotic woods like bubinga, jatoba, etc. So, before I go and spend the money, is this planer up to the task of dimensioning and finish planing these hard woods? I've read some bad reviews about the Dewalt knives wearing out rather quickly but then read about some aftermarket knives by Infinity that are supposed to work better. Anyone have any experience with this?
