Building my first HO layout (4x8 table top, 2 mainlines). Some of my equipment is pre 1950 Steam loco built by my Dad. No way I am taking those apart to try to add sound cards. My newer stuff none is DCC ready, hence my 7 block DC layout w/ 2 CABs. So I want to add some sound, I see lots of MRC discontinued attempts (#210, #312, #1025, Symphony 77, Sound & Power); keeping on eye on eBay for something reasonable - obviously if I want to spend big $$, better off going to DCC. But the reason I built this layout was to reuse my late father's equipment he built as a young man. Late in life he started to look at doing some modelling but never got back to it before he passed.

So - if I'm going to spend something under $100, any ideas what's the best option for the price? Am I missing another option besides MRC (Sountraxx early stuff looks limited). Newbie appreciates any help from folks who have done this before. And DCC is not an option I am considering (have 6 steam or diesel loco's now, not looking for any more). Thanks
