I recently gave my two new son-in-laws each some traditional-sized gear to get them started. Each received a diesel and steam engine with 1990s vintage TMCC along with a string passenger and freight cars for each. Also threw in some switches, track, and PW transformers with fast-blow fuses and TVS diodes, so they're good to go for Christmas and beyond.
I've been thinking about getting them a Command Base and Cab1 as Christmas gifts so they can use their engines in TMCC mode, but realize those originals are mainly available on the used market. I recall Lionel makes (made?) a Legacy era version of the Cab-1 (Cab-1L???), but wasn't sure if they made a newer TMCC command base or if that was simply the upgraded Legacy Command Base and now the Base3 and Cab3.
I'm still using an old TMCC command base (and have a back-up) with DCS and, lacking Legacy engines, never saw a need to upgrade to a Legacy command base. Anyone see a reason for me to upgrade?
More importantly, with my son-in-laws, would it be worthwhile for them to start off with newer Legacy or Legacy3 technology? Or would it be better to just get a used TMCC set whose prices on auction right now are a bit shocking, but what isn't these days?
