I also found this site describing a home-brew solution, and it has some nice technical details: http://www.cedarnet.org/smartware/Hardware/IR_Repeater/
My general rule of thumb is that, if an electronic product is widely available commercially and if it comes pretty close to meeting my needs out of the box, then my build/buy decision starts leaning pretty strongly toward "buy". I'm unlikely to be able to build something that's much better or cheaper than what's commercially available, even if what's commercially available is somewhat overpriced and somewhat mediocre quality. So personally, I'd probably buy something, but don't let that discourage you from attempting the educational and potentially fun satisfying experience of designing and building your own device.
