I've got the XIX Century Warehouse, it's very good. It's an extremely solid constuction, far more so than pretty much any other HDF building I've come across. It is a rather more complex build than other manufacturers though, with a large number of small connecting pieces that can be a little tricky to remove from the frames - but oon the whole I'd recommend them, the range is quite small though, with only three structures, the warehouse, an appartment building & walkways/stairs/gantries.
