I've never used nor handled a Lapin puukko before. But I just wanted to add my opinion on what foxhunter said about the knife not having a potruding tang.
I have a Karesuando knife that also does not have a potruding tang, and I have never felt the knife inadequate for cutting jobs. I feel that for as long that you don't use the knife in batonning, it should be fine.
The price point of the knife suggests that it might indeed be poorly finished, but leaves you the opportunity to do some work on it to make it more your own (sanding the handle a bit, polishing/reprofiling the edge,...)
It all depends on what you want out of the knife really... As long as you keep it sharp, it will cut
