Welcome Scowill, you may find the scope you're looking for in the Sales section here, however, you will need to make 5 or 6 posts on here before you get access to that. In the meantime, enjoy the banter and wealth of information. I'm seriously thinking of getting a HW100KT myself at the moment so would be good to hear how you get on with yours
