I only have 2 but they are great.
MTH. SP. from the late 90's, a great engine, no problems ever, a real smoker. Railing version, cost $250.00
The Virginian is a K LINE MODEL I bought a couple years ago, a great engine, strong puller, no smoke which is OK. Cost $100.00
I would recommend either , but ,K Line are used and only on Ebay*
