A Telstra salesman knocked on my door on Friday night asking if I'd be interested in signing up for Telstra cable internet.  I don't know a lot about cable, other than (I think) it's faster than broadband and obviously uses a different cable.

He asked me what I'm currently paying for internet and phoneline per month, which I estimated at $33 for broadband and $40 for phoneline (I didn't have bills handy).  He told me he could switch me to Telstra cable and phoneline for $10 cheaper than that. 

I'm currently with Xnet (with a 9GB cap that I never reach, but only pay for what I use) and I'm very happy with their product and service to date.  I have a Telecom phoneline and make only the occasional cell phone call on top of the monthly line rental, and feel no particular loyalty towards them.

The Telstra chap told me that cable is much faster than broadband (I think he said 10mbps?), and that the 'special deal' he was offering me would apply to the same data cap that I'm on, and that I'd only pay for what I use (right down to $0 if I didn't use it one month).  Apparently my neighbours have recently had it installed, which means for me the installation will be free.  There is no contract period and no disconnection fee, meaning I'm free to leave at any point if I'm unhappy with it.  I can keep the same phone number.  He told me the 'special rate' would apply for at least 3 years, so they would not be jacking the price up on me.

The unusual part is that he said he'd tried visiting me 3 times but I mustn't have been home, and he'd made a special trip at dinner time to catch me.  He wouldn't leave me a business card or a contact phone number (just a first name), stating that this deal was not available to the general public and I wouldn't be able to find information about it on a webpage or by phoning a number.  He said he would leave me the weekend to think about it, and be back on Monday evening with a form for me to sign if I choose to go ahead.  He was wearing a Telstra uniform.

My situation:  Alcatel Speedtouch 510 broadband modem -> Dlink DI624s wireless router.  Connected to the network is a laptop running Vista; Macbook Pro with OSX 10.5 and Windows 7 dualboot; Xbox 360 (used for the occasional online Forza race); PS3 (patiently waiting for PlayTV to arrive).

Obviously I like the sound of saving money and getting faster internet!  I'll have to phone Telstra on Monday and ensure that the salesman is legitimate.  His first name is disctinctive enough to go on. 

Is it too good to be true?  If it's for real is it the right move to make?
