Titanium Frames? Weis vs. No22 vs. A-Frame vs. Waltly

I'm looking into titanium frames. There's not much info online comparing the options. Anyone have any opinions? I'm particularly drawn to the A-Frame Track, as it seems like the most cost effective, but I'm unsure how it stacks up to a Weis or No22.

Weis Hammer Ti ($3700)

No22 Little Wing ($4300)

A-Frame Track ($2500)

Custom chinese manufacturer like Waltly ($1500-$2500?)

There was also that recent post about a potential ti frame from State, which is definitely interesting. Curious what the price will be / what the timeline is for release.
