Canon 70-300mm ƒ/4-5.6 IS USM ~$630
The previous version of the Canon 70-300mm wasn't an L-glass lens, but also offered image stabilization and USM focusing - and a much lower price tag. It also offered slightly better results for sharpness; the new lens, on the other hand, offers better tolerance to chromatic aberration. Results for distortion and lens shading are similar between the two lenses. The build quality on the new lens is in a different league, being an L-class lens.
Conclusion
The Canon 70-300mm ƒ/4-5.6L IS USM didn't produce tack-sharp results, but it produced a consistently good images at each focal length, with good control of chromatic aberration. While you can certainly spend less money to get the same range of focal lengths, the build quality and technological supremacy of the Canon reflects the price point - it's a lens you won't be afraid to take anywhere.
