AP client

Currently, I have DSL and a Linksys WRT54G wireless router in one room. Now
I need to hook up a couple of desktops in another room (see diagram below).
What is the cheapest way to accomplish this?

1. Can I use an AP client? That way I only have to buy one device. Is it
possible to convert a wireless router into an AP client (since they're
cheaper than the WAP11)?

2. Could I forget about the wireless approach and buy another DSL modem to
put in the second room? Is it possible to hook up 2 DSL modems?

3. Wireless bridge pair. I don't really want to go with this option because
I would have to buy a pair, which would be much more expensive.
