I think the bridge is very neat. I appreciate the fact that Lionel is offering new products that meet a need for hobbyists that may not be able to engineer their own lift out section. I also appreciate that it works with all track systems, and that the piers are configurable and flexible. I don't have a need for one right now, but I may buy it to keep for when we eventually do another layout.
As to the price, I noticed it was not inexpensive but once again, and not to sound like someone who doesn't have bills and expenses like everyone else, it surprises me that folks who routinely spend hundreds of dollars a year, if not more, on additional locomotives (that none of us need, btw) would balk at the catalog price of an item that is new and very innovative. If I had to pay the $300 for the bridge, I probably would on the theory that unlike the locomotives, the accessories can actually be one-off and done for a long while. In reality and as people know, the street price will likely be a good deal lower. So as I said, I am not sure where the criticism originates -- costs for everyone are higher across the board and this is just another example. Do I like it? Nope, but I will budget accordingly and not allow it to dampen my enthusiasm for the product or the hobby in general. The only question with respect to this item and others is really can I properly afford it? No different than any other consumer item.
For those who can build their own structures, that's great too and a terrific part of the hobby as well. But I wouldn't mock others who would pay to have a nice bridge that they themselves probably couldn't replicate.
