Piper Seneca

hi all!

This might be a silly question, but I am dreaming of owning, or co-owning a
Piper Seneca.
Not this year or next, but maybe within the next 10 years.

I have been browsing the aircraft for sale sites, and found planes from the
70's (Seneca II) selling for as low as $139K with about half time remaining
on the engines and props.

Anyone care to share the pro's and con's of the different models? (I-V)
Obviously, I will not be able to afford a V, so far, only the II's seem
accessible sort of.
Anything worth knowing about this model? Bad things?

Also, I understand maintenance will be about double of what I have now
(Arrow 180).
Any other traps to consider cost wise going for a twin?

Any other aircraft in the same price range that might be better choices?

I'm looking for a piston certified for Icing conditions.
I also want a twin, as I'll be flying over mountains and have nightmares
about engine out's in IMC and icing conditions over mountain terrain.....

Thanks for any hints,

Frode
