If a video game router will work, you can use an old Linksys router and re-flash the chip with DD-WRT and turn it into a receiver. You can find them in the classifieds all day long for 10 bucks. DD-WRT is available free online and the process takes about 30 minute the first time, another 20 minutes reading the instructions and setting it up as a receiver and you're good to plug and play. Works on video game consoles too (which is why I can never find the two I have)/ PM me if you need more details.
