get a sig 4-star 40. good instructions, excellent handling, simple build. and the structure is very tolerant of inexperience. if you warp the wing, you can shrink it out when covering. not much sanding. they come out light. It is not "new and improved", just a good plane. they are laser cut now, also, which is nice.
I wouldn't necessarily recommend a g.p. kit for first build, as they tend to come out heavy if you aren't careful. and sheeted structures, like most g.p. stuff and the tiger from goldberg (an excellent flying plane, by the way) are difficult to un-warp if you mistakenly sheet one in. I say build a 4-star, and make your mistakes on that. then build anything you want; but take it easy at first!
now, I'm a builder, been building since 76 and controline and rubber before that. and that's my 2 cents worth!

but ask around and ask about sheeting, weight and the like and take your best shot; AND- build what you like, regardless of what me or anyone else says; it is your plane!!
