.io registrar

Does anyone know of a competent .io registrar who charges in the <= $75/yr area ? I've been using tierra.net (domaindiscover.com) but they continually break my domains. this year, although their website says my domain expires 4/2012, my domain stopped working today. the .io servers aren't serving records, and nic.io says the domain expired 4/8/2011. i got a hold of them this morning got a ticket -- but after 4 hours still no response. also, although nic.io lists a bunch of .io registrars, when I called them they almost all say "we don't register .io" :D -- Jeremy Kister http://jeremy.kister.net./
