Check the warbirds forum for Skyshark comments.
From what I've read they're top-notch and make real quality products.
If this is your first kit, I'd go for the Skyshark Fantasy, it resembles the SIG 4*60 and will be an easy build and learn you some basic techniques.

I buit a SIG 4*60 as my first kit and it's not hard at all, goes together very easy and you frame it up in a few evenings.

My advice is that you first build a SIG/GreatPlanes/Skyshark sportflier to get the hang of building before progressing to a nice warbird or larger scale aircraft.
