After reading the intial flurry of messages regarding Comcast accepting hi-def service orders, I took the plunge and started calling.
*** One big tip: if the CSR you speak to insists that they're only testing, hang up and call again. ***
The first two guys I spoke to late this afternoon insisted that there was a select pool of 600 users in the Chicagoland area, and service will launch to the general public sometime during the summer. I got a little frustrated, so I hung up and made myself some dinner. I guess there was a shift change around 6:00 pm, because I called again and spoke to a rep named Mike. He said I was his first customer to sign up, and yes - they were just informed about the program today. It took him a while to schedule a service call for me, but I was more than happy to spend the extra minutes on the phone with a guy who was willing to sign me up for the service.
As reported in other messages, the cost is $29.99 for installation and $5/month for box rental. I already subscribe for the Platinum package, so there was no additional charge for HBO and Showtime.
Can't wait until next Wednesday, sometime between 1:00 - 5:00 pm.
