dont be worried about flashing..buffalo routers are meant to be flashed..infact there is only a minority using buffalo routers w/o flashing with custom f/w.I used tftp to flash it with tomato and have been very happy since..IMO DD-WRT has become too bloated with extra features. Havent tried openwrt. BTW hyperwrt-tofu ; hyperwrt; hyperwrt-thibor and tarifa work only with Linksys products.
