On my D-105 layout I went with all PW accessories for the usual reasons. The look, style, and authenticity. This was also for signals, structures, and transformers.
I will say that the acquisition process is a slow one. In fact, it took me close to a year to find everything in the condition, and price, I wanted. That's a combo of local buying, York, and Ebay.
But...I will say it was also one of the best parts of the whole process. Actually had a lot of fun on the hunt.
