I went and bit the bullet. Now that I have over a hundred miles on it, I can give some impressions.
For background, this is to replace my 2002 Lemond Maillot Jaune. The frame cracked near the rear derailleur-side dropout, with cracks in the rear rim as well. I was depressed about it for a few days, all the while my wife saying "upgrade opportunity." After the mourning period, I finally listened to her.
I had been considering Habanero for while, after discovering it while googling for peppers. The reviews looked good. So, I exchanged a few e-mails with the owner of the company. Mark is extremely nice, and went out of his way to be more than fair with every aspect of the transaction (even when, in my opinion, he didn't have to). They have many of the companies I deal with beat on customer service (bicycle or otherwise).
So, I ordered a road frame with Ultegra components (10 speed).
A week ago today, the box arrived. It took me the better part of two hours to get the thing ready to ride (wheels in position, handlebars and seat post bolted in, computer attached, etc.). This is mostly due to my own disorganization, a 18-month-old daughter, and a 22-month-old cat (they have a serious sibling rivalry thing happening). Oh, there is my own excitement. I managed to pull a valve stem out of a tube trying to inflate the thing. Oops.
It rides like a dream. I have never had a bike that was so stiff yet comfortable. I can climb better than I ever did on the Lemond (even before the chainstay started to go). It is very smooth and responsive.
I expected it to be heavier or break even than my Lemond. Though the frame was lighter, the Lemond had Dura-Ace (older) components and Race X Lite wheels (the Habby has 32 spoke Mavic Open Pros). However (and I have not put it on a scale), it feels lighter (many who have picked it up agree).
I admit to being a bit of a retro-grouch. This bike has many features (conventional design, pump peg, etc.) that appease that need, while keeping modern touches I appreciate.
All in all, a great bike, and a great deal. I'll post after I have a few hundred more miles (and hopefully a century) on it, to see if this is just new bike excitement, or a great rig.
