I have never used the bitcoinvanitygen service and cannot vouch for it, but the website says it's free. If you try it I'm interested in hearing how good it is.
http://bitcoinvanitygen.com/I'm trying it out. I'm currently on the queue.
Though the limits are pretty low. Only 5 letters vanity and 6 for no case sensitive.
its pretty resource intensive to generate anything higher than that you could just install vanity gen on your computer which is a simple program to use and that would tell you the same thing 5-6 is the sweet spot.
Yeah. Ok, just got a vanity address from that site, sent to my email and was pretty fast.
Although if you deposit bitcoins in there no one can guarantee the generator site won't steal your coins from you, so that's a concern.
I'm using mac with OSX, is it possible to use vanitygen?
