I’m aiming at Huskquarna Viking Machines? there is three model I’m looking up. it’s 830,850,870. I would like infomations from you regarding of these machines if you own its. the reasons is I have read that there is problems with tensions, which I don’t know if it’s true. the machines is supposed to be made in sweden. now they are saying it’s made in other countries and the tensions is causing problems in these kind of model machines. so before I plan on buying it for clothing alterations. just wanted to make sure I’m not falling in a bad traps with a poor quality machines that just won’t do the sewing abillity. I beleive one person have told me she loved her vikings in alterations post it area. I will have to contact that person once again and see if the machine have ever given her problem. thanks in advance.
