AT&T Yahoo! DSL Internet package

I help my parents in law to sign up for DSL Internet service from ATT
They use Dial-Up previously, cost them about 10 bucks. Now the AT&T Yahoo! High Speed Internet Basic Package is $14.99 per month with following features:

Speed: 384 Kbps to 768 Kbps downstream / 128 Kbps upstream

ATT has four different packages for residence. The other three packages are shown below:
Express package:

Speed: 384 Kbps to 1.5 Mbps downstream / 128 Kbps to 384 Kbps upstream

.


Pro package:

Speed: 1.5 Mbps to 3 Mbps downstream / 384 Kbps to 512 Kbps upstream

Elite package:

Speed: 3.0 Mbps to 6.0 Mbps downstream / 384 Kbps to 608 Kbps upstream

For the basic home use, I trust Basic Package is good enough.
