I've got 20hrs in a PA38 and would not recommend it. It's OK to learn on ("you learn PROPER flying, young man" kind of thing) but the thing is so unstable that it's very tiring to fly it for any distance. The stall behaviour (a rapid wing drop followed by an exciting plummet) is not too safe IMHO. And it makes sense to learn in a type which one will be flying afterwards. No substitute for currency on type.
