I have been considering an aftermarket firmware for my Linksys WRT54G mostly because I am interested in playing with the bandwidth settings (to see if I can get the VoIP working better) and, of course, to play with the power settings to see what they will do to range, throughput, etc, etc.. I was considering using the sveasoft firmware. However, reading the posts here and on their website, one has to conclude that the chances of successfully uploading the firmware AND have it work afterwards is no better than 50/50. Perhaps that is being pessimistic, but if you google "satori" and "brick" you get a LOT of hits. Add in "suddenly stopped working" and you got yourself a good afternoon of reading. I suppose you just have to include the (possible) costs of buying a new router into your calculations.
