I recently got a Cinelli Xperience after years of riding steel bikes exclusively.
The frame is crazy stiff, and really jumps when you stomp on the pedals. Handling is superb, provided you set up the front end properly. I started with an 80mm stem and the bike was way too twitchy in the corners. Going up to a 90mm stem added a lot of stability. It's not particularly light for an AL bike, but the Zonal tubing should be more durable than Starship or Spirit. All around, a great frame for the money.
Some things to remember: it's designed as a race bike. There are no fittings for racks or fenders, and the tire/frame clearance is INCREDIBLY tight. Don't attempt to run fat tires on this thing. Also: it's designed as a race bike. If your roads are anything besides baby's-butt smooth, you will feel everything. The bike takes a lot more out of my upper body than my steel bikes do.
All that aside, it's my favorite ride. It climbs like a monkey on meth, and rails tight corners. If you want a true race bike with over-the-top Italian style points, you can't go wrong...
