Hi all. I am looking at finally up grading to DDC. As my layout is HO 1940's era it is all steam. My question is, I have a Prairie 2-6-2 item #51524 and a USRA 0-6-0 #50606. Is the conversion worth while on these 2 (less than an hour runtime on each), or should I put them on E-bay and look at DDC equivalents ?

Thanks for your help.
