You do vanity "mining" with a GPU. If you have an ASIC, you could put the income generated as bounty, but i think that Avalon is quite obsolete, so you might as well just give the vanity gen a try with whatever you have on your PC.
Thanks for reply. I've already tried to do with my GPU but it is no so fast.... So, if I buy it, I can't use with vanitygen? And with oclvanitygen? Is compatible?
You need compare GPU's here is a list:

A big thing is how long of vanity address your "mining". Depending on length and if exact it could be a very long time, or very short time.
Best bet is selling the obsolete miner, then using the BTC to put up a bounty to get the vanity address. Afaik you can't roll priv keys with ASIC, but maybe someone figured out a way to do it, if its even possible.
It was not when i tried it though and if it is, it should say it does in the readme, however google says nope.
