depends on what you're looking at and comparing to: Ofmega was a "2nd tier" component line that offered the buyer a lower-cost alternative to Campy, it was lower cost for a reason (not made in China, so same Italian labor costs). Some of the materials were lower grade, sometimes just the finish was lower. I happen to like the Ofmega touring triple crank that was brought in the US under the Avocet label, likewise their 2-bolt seatpost...but not a big fan of their hubs, and don't know about their pedals. The reason Campy is considered "rebuildable" is not just the design: they made ALL the parts available as spares, and for a long time (but don't ask about the hub races) and tools as well, they provided after-market support for their dealers and customers. Some spares will be available for Ofmega stuff, but a lot of the time you'd probably find Campy parts (those that will fit) more readily. I have a lot of Ofmega chainrings on Campy cranks (and lower cost is why), the only thing I'd completely avoid is the weird plastic derailleurs in '80s pastel colors.
