I carried a 1024 bit key for 5 years (2004-2009). For me it was easy to change over to newer size in 2009 because never been able to get my key signed.  Next set made use of sub keys, in hopes of futur getting them signed, and just using bigger/better sub keys as need arose.  Alas, 5 years later and still not found any other gpg uses so no signatures.
