Hi Graham
Welcome to the forum
It all depends on your intended use of the machine but if you are intending to use it in anything resembling serious production you might want to have a rethink, best bet would have been to have a look @ some of the build logs here on the forum to get an indication what is actually required to produce a solid reliable machine. just had a quick look on youtube and not impressed with the machine.Don't be put off though the guys on the forum will point you in the right direction.Rule number one don't buy any kit until you have a design drawn up.best bet for now is read the build logs, there is a wealth of hard earned information on the site.
Good Luck
Regards
Mike
