[Elecraft] 500Hz 5-pole vs Inrad 500Hz 8-pole?

[Ross Primrose]

Any thoughts on the merits of one vs the other? The 5-pole filter is 
cheaper, but they need to me matched for diversity receive, does the 
8-pole Inrad filter not need to be matched? Is either one/both wide 
enough for 500Hz Olivia modes?

Thanks...
