If you aren't worried about your LBS losing out on your business for this one, then I highly recommend having Xtracycle send the frame over to GVH bikes. Check them (actually, him) out at http://gvhbikes.com

When I bought my frame on Ebay, I had the seller send the frame directly to Tom (the GVH guy), and he built it up with the components of my choice. The price on the components was better than I could possibly have gotten buying them anywhere else, and the assembly was only $75! Shipping was only $55! It was sooooo economical, and he was very speedy. He sent out my bike in less than a week from the time he got it. And he did an absolutely first-rate job. He really loves bikes and puts his heart into it, you can tell. I haven't even had to tighten a cable since I got the bike last July!
