The first question to answer is: Is this frame going to fit my body properly? If you don't mind my asking, what is your height and inseam (yes BFers this won;t be cycling inseam but close enough).
The Sirrus frame is certainly worth holding on to. You might put $75-100 into it between tires, cables, bar tape, a new saddle, brake pads, etc. Maybe not even that much if you have local co-ops to provide at least some parts.
You're definitiely right, those Scott aerobars are not stock. However, if push comes to shove, I'd trade you a set of standard drop bars for them. I'd even make up some of the shipping difference since your bars will require a larger box. Just food for thought.
Other than that, two things: 1) this is a very small frame, you should probably be no taller than 5'6" for it. 2) in the first pic the handlebars aren't straight and the fork looks a little "funny". It may all be perspective but any chance we can have a dead on side view with the handlebars centered? I'd want to be sure it wasn't in the trash because of a bent fork.
Oh, and welcome!
