I bought it recently so I've only opened the box and drooled over the contents so far. It looks very nice in the box, and it's definitely quite complete. You won't need any aftermarket parts at all.
One thing you will need though, is a good reference or two. Karaya assume that you're something of an expert on the subject so the instruction leaflet is rather thin on information. It'll allow you to finish the kit, but some small details and colours will be somewhat mysterious without outside help.
The kit will take a bit of "some modelling skills required" but I'm going to enjoy building it
