Transformer for Digitrax

[Nick8564]

What is the best transformer I can get for the best price for a Digitrax DB150 command station even if I have to build one. Thanks

Do you have an old DC power supply? I use my old MRC Control Master 20 and it has done the job for me as well as supplying lighting for my buildings. A good old workhorse.
