Rapha, nice but a bit pricey?

Continuing the base layer debate from above, i still have an unworn PT short sleeve base layer that I'm debating over returning.

I got it at 20% off, but still, is a normal synthetic baselayer worth £40? To those that have one, are they worth the dosh?

I have two PT baselayers & wear one of them on all rides on warmer days
When it's cooler I wear my Brynje merino mesh.
Not sure it's £40 worth...but it is a nice bit of kit and gets used a lot.
