If you just want to spin records, the 1200s are fine - they are built solid. But if you just want reliability, why not CD or (better) MP3? Solid state can't be beat for reliability.
I've got no problem with Technics - in fact I've got the predecessor to the SL1200 myself at home, I think it's probably over 30 years old now (SL12 may be the model number?) and it works like new. It's been modified to play 78s which is nifty. Probably will outlive me.
But if you want to make music with records, truly create, you are short changing yourself not to look at some of the features on the newer turntables. I'm not a DJ artist - but don't get hung up in the "me too" underground DJ identity ("SL1200s forever") and overlook the powerful cool new tools out there for creative artists.
But maybe you don't aspire to creativity?
