25 years in "O" scale 2R and 5 years (off and on) in "S" scale and IMHO the SHS locos and rolling stock are right up there with the very best of any plastic RTR products in "O" and better than many. Very quality built models. My SHS F units do have a whine while running but as Rusty stated nothing objectionable and the accuracy is outstanding. My greatest fear with the MTH takeover is they will replace the SHS horizontal drives with china drives so they can fit their electronics inside as Lionel did with their new "S" products. I really, really dislike the china drive even though its better now with all the electronics controlling it than before. My new "O" 3rd Rail E7's have a very smooth horizontal drive that I think will overshadow the china drive in "O" in the future.....or not. I really don't know how the 3R guys feel about it and they seem to control the "O" plastic RTR market.
