Thanks guys & Girls for the replies, that's given me the information that I need so job done with regards to that.
Spruce, I appreciate your comments (constructive criticism they call it) and you are right it wont make a big difference for what its worth. However, I asked the question on here as I just wanted to know if the other guys used one and what the benefits were, the cost is no big deal.
Other than that I appreciate your post, as you have given me some good information, I am nearly their with wfp, if had more customers I would have jumped in months back. Its building up now so need to make the move and will do very shortly.
Thanks chaps
