Can anybody tell me if these are any good? I've posted a want add looking for some used SSIs but since they appear to be pretty hard to find in used condition I may need to buy a new set. The Bird sells dansk steel replacements for about $600 each which seems like a good price but I wonder if they'll fit and work as original or if Ill have to beat them into submission / re-weld them to make work. Thanks for any input.
