Wireless networking for Dimension 4600?

I'm considering a wireless setup for my home office, because I'd like to move my home office into a room without a phone jack.

I'm looking at a couple of options, both with USB adapters: 1) Netgear WGT624/WG111T and 2) D-Link DI-624/DWL-G132.

Any opinions on either of the above? Or other recommendations? I'm looking primarily for reliability and ease of use.
