I'm not criticising your decision to buy test equipment, it's laudable to want to do the job properly but I just wonder why, if BT engineers used to use a fairly simple USB modem and a laptop to determine line quality etc. that isn't good enough for you?
I can't see anything on that device that you can't obtain from a simple router or USB modem (apart from perhaps ADSL2+, does anyone do a USB attached ADSL2+ 'modem'?). The only advantage is that it's self contained but I'd be surprised if it's anything more than a router in a box with an LCD attached to a debug port for which you're paying a hefty premium.
The fact that you can't even download a brochure without registering for marketing e-mail off them puts me off as well, surely if the product is good then they'd share the details.
Again, really not meant as a dig at you, it just baffles me why spending more money than is necessary to get the job done seems to be required unless it's to baffle customers with bullshit (which may be taken as either a dig or a heads up for you)
