I can't comment on the Dewalt but I can tell you that I am very disappointed with my Makita, I used to have a Delta 22-560 which was fantastic until it broke, no snipe and a great finish and when it came to replacing it I read all the reviews and group tests I could find and decided to go with the Makita.
The most frustrating issues I have with this machine are:
1. I get snipe on the ends of the boards.
2. I clean the feed rollers and polish the tables before I do any planing and I can guarantee that after 20 minutes or so I will have to stop and clean them again as the wood (mainly Oak) starts to stick to the tables (this may be due to the tanin in the Oak but I never used to get it with the Delta)
3. The knives seem to chip very easily, I have never put any timber through that had a nail or staple in it but still they chip (a knot can chip them) leaving lines on the wood
4. I recently had a problem with lowering the head, it would wind up ok but to lower it I had to almost swing on the handle, phoned Makita and a few of their service agents to see if they had come across this before?
I ended up completely stripping the machine in in order to correct it.
NOT BAD FOR A MACHINE THAT IS LESS THAN 10 MONTHS OLD!!!!
ANYONE WANT TO BUY IT???
Sorry to be so negative (or truthful) but when you are parting with your hard earned cash it is best to know what other peoples experiences have been, perhaps I was spoilt with the Delta or maybe my Makita is the only duff one ever made.
Best of luck
