I've never heard of Spin. It looks like you can buy it direct on their site cheaper.
The welds look ok. The blurb says:
Custom drawn, cold worked, double butted 3Al/2.5V Ti certified aerospace titanium tube set
I don't know what that actually means, but a DB Ti frame for £800 sounds pretty good.
Thoughts?
EDIT: From the site it looks like it's the same tubing as a Van Nicholas Yukon. And the large has a claimed weight of 1500g... 10yrs warranty as standard... sounding better all the time.
I found this Ti frame on ebay:
