For the amount of table coverage you get I think these are quite pricey.
3 of these arches is more expensive than a Pegasus Gothic building kit (which is substantially larger) and for the same money they are not nearly as nice as the Thormallion ruins (Chamberlains corner etc).
If there is a discounted bulk set offer the value could be better than the other choices but as individual sprues, no. But then, it is another option on building ruins.
