My radiators are exactly 100 years old. They're leaky, covered in lead paint, and very large. I had the ones that we use actively repaired, but I was thinking about replacing the others with slimmer more European looking radiators or removing them.

The problem: Looking around for stores in the US that sell slim style radiators I mainly saw results from Hudson Reed, which have mixed reviews online. https://usa.hudsonreed.com/revive-dark-blue-horizontal-double-panel-designer-radiator-all-sizes-86597

My question: Are there any other reasonably priced US manufacturers?

There are a million options in the UK but so few in the US.

a wide variety of exciting european options:
