If you are having trouble sourcing nichrome, you can get it out of an old hair dryer. Unfortunately, I don't know much about the other candidates you mention. The most important thing is that you need some resistance, otherwise you will pull down too many amps, and short the PSU. 6 Ohms is about right.

jcabrer:
Unfortunatelly I don`t have suitable appliance at hand to source nichrome wire. I have finally bought isotan wire with 10Ohm/m, as far as I remember lenght of 30cm was recomended, so 20Ohm/m would be more suitable, but was out of stock. My biggest concern is how long will isotan wire last operation at required temperatures, but I will try and post results.

It should work just fine. But winding will be a bit more difficult as you will need 60cm instead of the 30cm.
Probably it will work longer than nichrome, because the temperatures of your wire will be lower (because it is longer).
Is it insulated wire? If not, how are you going to insulate it?
Always measure the resistance after winding, and before hooking it up to the electronics!!!
