Can anyone help finding a decent sports bra?

[BlameItOnTheBogey]

I think I am looking for the impossible. Or it sure feels like it. Requirements are:

• Needs to come in a 30 inch back (rules out 90% of all bras immediately)
• Must have shaped cups and not the mono-boob, squashed look
• Needs to be at least medium support.

Is this a totally impossible quest? I just want something that doesn't look awful under a vest. Anyone founds anything like this? Or know where I could look?

Just to say I found the shock absorber one almost impossible to get on and off. The one for bigger cups for running.

I get all my sports bras from a website called "boobydoo". They have a really wide range of sizes/styles/makes, usually deliver the next day and usually free returns. also, the package is small enough to be posted through the letterbox so no waiting in! Lots of helpful info in the customer reviews as well
