Turbo anything is not a good idea for training - much more cost to repair. Apache was a good plane for twin training - getting more difficult to get parts and costly to repair unless you are a mechanic and have a place to work. 310, Barron - travel air - all can be more dangerous for twin training - get a plane that is easy to fly - forgiving- and not as expensive to repair or operate. Keep the plane light - no observers - Don't buy cheap - the plane will be broken all the time or you will be "broke" trying to buy the parts to fix it ! Get a good plane - spend the $ - forget about all the fancy avionics - stick to basics -get the ticket - get some time- and move on to the fancy stuff later.
