Keep in mind, there are no perfect boards, but try to always use the straighter boards and avoid warping boards. Also, Brandon and I have found that when it comes to picking out lumber at Home Depot and Lowes, they tend to stock up on fresh boards a few days before the weekend starts (so Thursday/Friday). And then, on Sundays and Mondays, the boards are usually really picked over and there isn’t a good selection. Just another tip to keep in mind!
I could not consider a 12" jointer, given that the equipment had to be moved down the stairs to my basement, and the cost would blow my budget. What I wanted in an 8" jointer was true tables, a fence that is solid and easy to adjust, a cut depth gauge that is reliable, and long tables that aid in flattening longer bowed planks. I have found that the Taiwanese tools have come a long way in the past 20 years. I purchased the King KC-80FX 8-inch jointer, with lever adjust parallelogram tables. The system arrived in a good state of tune, and the well-written manual includes a full parts list and exploded parts diagrams. The tables were extremely heavy; more about getting things down the stairs later. The jointer is reasonably priced, it runs smoothly and it is well made.
