I currently have a Foundry Chillkoot and so far so great. It rides great, looks great and I don't see any major quality issues. I don't see any reason to be scared of titanium or any material in capable hands. Certainly titanium is a harder material to work with and you would be best going with someone who knows what they are doing but there are so many out there it can be hard to choose.

The scary part for me is lusting after a Firefly Ti All-Road bike but not sure what parts I would put on it and if I didn't do something would I want it later. If I could have my way my fleet of bikes would be doubled and half would be high quality steel and half would be titanium (currently three steel bikes and two frames, one Ti bike and two aluminum bikes) or at least they would stay the same number but I would replace the aluminum bikes with Ti and upgrade the crap out of it.
