I recently built up a Nomad. I am in USA so my parts sources are quite different. I found a double Vuelta Corsa Comp square taper crankset for less than a typical set of crank arms. They are available in both 110mm and 130mm, so if you order one, be careful to order the right one. It was actually cheaper than the price of some chainrings. I am not using the rings that came with it, instead I am running a chainguard/bashguard on the outside and the chainring on the inside.
My chainline is roughly 5mm off, which I am quite content with. If I put the chainring in the outerposition, it would be just right, but I prefer to have a chainguard in that position. I knew that it would be off by about 5mm when I ordered the bottom bracket, I did not want my pedals to be more than about a half inch (about 12mm) wider than on my other bikes, thus I intentionally have a non-perfect chainline.

If I go somewhere like I was at last year where there could be some mountain climbing, I would put the 44t on the outside and 36t on the inside with no chainguard. Then when I knew that I would be climbing for several tough days, I could remove a few links from the chain and switch rings before I embark on the mountain climbing.
