Sorry, It does not make much sense as to why someone would pay more money for something far less. Nothing wrong with their kit, appears to be a good kit for someone with very limited funds. My math might be off however it shows that their kit is 500 pound more then ours. I guess theirs would be a good thing if it was selling for 3000 to 4000 less then ours.
Just do you homework, you get what you pay for no matter what Country your in.
