Browser support for Gradients & Filters

I would like to use Gradients & Drop Shadows in my design, considering that any browser except Chrome is going to perform a poor presentation of my website, what would be the best way to maintain a similar look accross browsers?

My Solution: "Use PNG with transparency to create gradiants and filters, detect the problematic browsers and redirect them to the solution website,

Concern: Loading time for all these images to load into buttons & backgrounds.

Any other solutions or ideas?
