Rapha, nice but a bit pricey?

I've literally received an Albion jacket this week and the sizing is very different to Rapha, for jackets at least. I'm a M in Rapha these days (used to be a L but size classification has definitely changed over the years), ordered an XL Albion jacket and the fit is just right. I did look at their size guide, which gave some useful measurements and meant I got the right size first time.
