Buy it, put it in the glove box and forget about it. Ive put a combined 340k miles on three different psd's, done one cam sensor. Honestly the first thing I would do, is STOP reading about them online. Theres so much bad info and horror stories online thats its almost pointless. Just get it drive it, see if its got any problems and go from there. They ARENT complicated or hard to work on, most people who think they are, are scared of change and hold onto the past for dear life. My 2 cents.
X2 on this.
Once you get use to a PSD you will find them easy to work on. You might run into a stumper, but with a little thinking or cheating with a scanner you will figure it out.
