For me, a jointer is an absolute imposibility. I do have the DW 735 which does get a lot of use. I get most of my lumber rough cut and sometimes the board might be 1-1/2 " at one end and 1" at the other. Sometimes there will be a pretty good twist from one end to the other. There are many reasons for not making my first milling by running thru the planer. Sometimes, I have taken a couple of straight 2x3 clamped down to MFT and to either side of a board, then a piece of 3/4 Inch plywood to bottom of my router with a 3/4" flat bottom cutting bit and slide the router back and forth across the two rails. If i miss a couple of spots here and there, a quick fix with chisel or block plane and i am good to do the parallel face with the planer. Later on, I bought the Festool power plane and flatten one side with that. i get as close as possible, but sometimes go to the handplane and winding sticks for final flattening. this is a bit quicker and cleaner than the router method described. Sometimes, i just use a handplane for flattening the first face. I don't think you could go wrong in getting a good thickness planer and a good hand plane, but I think there are a lot of other toys you can get and learn to use before getting a jointer. My opinion is that if you go for the jointer, wait til you can afford a stationery model. You can get into a lot of trouble by trying to use a jointer before you learn what is happening when you mill with basic processes and tools. In my case (not for everybody), I do not see ever getting a jointer. (I have used them from bench models to 8" long bed. The larger the better, but there is no way to get one into my shop space)
