Want A Project Bike - Need Advice

I previously posted a picture of my 1979 Triumph Bonneville in the Newbies Forum that was restored by someone else. Now I want to do my own project bike. Maybe not restored to original condition, but one that runs and handles well, and at least looks good from 20 feet away.

I almost mis-stepped already, bid on a Triumph Tiger on Ebay, then it dawned on me that it has been severely been altered, and was missing a lot of parts . I want a complete bike, with all the original parts, I like the classic look of Triumph unaltered.

My mechanical ability is OK, nothing to brag about, I have maintained old autos to some degree, took a class on auto engine rebuilding and auto electrics. Reading all kinds of literature to bone up on Triumph mechanics and nuances . Also got a copy of "Building budget brit bikes" book. In a perfect world, I will do this in my retirement years (maybe 5 years from now) but I may not have the patience to wait.

I am in Austin Texas, I don't see any Classic bike sources like swap meets etc. but haven't really looked that hard either. I used to go to swap meets on used Harley stuff, there are plenty of those around.

I am looking for good sources for Triumph parts and or bikes for sale, and if buying online, someone I can trust. I would welcome any advice to steer me in the right direction
