Search ebay for "RA_1 clone" and eventually you'll be viewing a number of "Cmoy" type portable battery-powered amps, some of better quality than others are...
I'm not affiliated with this EBAY seller, but check out the one who calls himself "biosciencegeek". He'll make you a high quality "RA-1 clone" (using the exact same op-amp that Grado uses) for not much money.
