I have found that it is still possible to get Titanium byrds if one looks around. I think one of them is available at the SFO, and it's marked down presumably for closeout to a similar price as some of the big knife vendors online.
I got a Cara Cara 2 and Meadowlark 2 and they are very nice. lighter and thinner than the SS version, a bit grippier, and still feel just as solid. thinking about swapping an Emerson Opener CC2 and a Hawkbill blade to each, respectively. will post pics if it works out - I saw a pic of a Ti Meadlowlark with a hawkbill blade on the "Which Spyderco is in your Pocket Today?" thread and really liked it, so I just ordered some blue loctite wax and soon I will probably swap them.
And I completely agree, byrds are great for their price. If it weren't for the advanced steel and awesome designs spyderco has, I would be pretty torn between some similar models. Really glad that both exist.
