I have the Porter Cable 4216 jig that is simple to operate without a very steep learning curve, which is good for anybody that is partially brain dead like I am.
Seriously though the PC 4212 or 4216 jig is a nice jig and will serve anybody very well and for the cost is well worth it due to the wide range of plain and decorative dovetails and box joints it will produce. It really is very easy to set up and operate with a couple of practice runs.The one thing that is almost required with the PC 4200 series dovetail jig is the supplemental instruction booklet that is free from several places on the net. I will even post a downloadable PDF copy if asked.
When something is advertised as being foolproof there is always a better class of fool that comes along to prove them wrong.
