I have not seen the Black Hussar one but I have seen the Perry one. I was very impressed.
As said, though, pontoon trains are very much 'blue moon' purchase - you know you want one, you know you need one, but you don't know (outside of a single scenario, some possible campaign usages, and to add to general baggage) that you'll actually use it very much. I just couldn't justify the purchase when so much more useful shiny stuff is on the shopping list. If a good MDF one was on offer, given it generally brings the cost down by 50% more people would probably have one.
