It's a constant issue for me as well, but still worth the time and energy expended. I priced some external hard drives today and read some online consumer reviews for that very reason. I ended up just buying a 100 spindle of TDK CD-Rs that were on sale for fourteen bucks.
I have several other computers besides the XP I'm writing this message on, but they are all Macs and none of them even have OS X which is a minimum requirement to use Tomato or one of the other Mac-based clients; it would be nice to get at some of that hard drive space. Sometimes, I shuffle files around all the other hard drives though.
, please join me in the future and add any torrent announcements here to this thread for any shows that you see that look particularly good.
