Ektacolor is not Ektar.
Ektarcolor Pro 160 is a 160 speed colour negative by Kodak distibuted in Asia and possibly France iirc.
It's extremely cheap on ebay, its currently $2.16 per roll including delivery for 120.

160S, 160C, Reala, 400H, 800Z are all still available fresh and will continue to be.
I've got a whole bunch of Ektacolor Pro 160 sitting here, I've yet to develop many rolls of it (I do my own C-41, sometimes in very odd processes), but it seems pretty good so far, not that you have much worrying to do in 120, colour is nice.
Pro 160S is about my favourite film, Reala is also excellent, no point in wasting these films on learning on though when you get something that's still very good for much cheaper.
Ektar is a more contrasty and colourful film than these portrait films, I've seen it used for very beautiful portraits, though this is with extra lighting, and controlling lighting ratios, not with available
light. I wouldnt use it for available
light portraits.
