And even then as puppy says you don't get a seneca type rating
No, but you will get "hours on type" which could be important with regards future employment and insurance requirements.
I have also heard it said that training in a turbo'd twin (Tayflite use the Seneca II?) is more valuable for low houred pilots as it teaches engine management from the word go - as opposed to firewalling / yanking back the throttles whenever you feel like it.
