I am going to buy a bunch of tools right away and am pretty sure I will just upgrade to a Leigh dovetail jig and sell the Rockler. What are your opinions of the 2 models? I am not sure I need 24", but have read some reviews that say the D4R is easier to set up and use. The 18" Super is about $200 cheaper than the other which is a sizable amount of money. However, I also know that once spent the money isn't really noticed. So I want to buy one that is the easiest to use and will allow me to do the job the best. For those of you with experience which do you think?
