Duenstar also has single band filters for $73.00 each.
Here's a report on bandpass filters I prepared a year or two ago that ran in National Contest Journal.

Also look at

http://k9yc.com/Coax-Stubs.pdf

for practical info on stubs, how they work, and how much to expect from them.

I strongly agree that the 5B4AGN group purchase kits are a huge bargain, and their performance blows away all but the W3NQN filters that Array Solutions sells for a LOT more money. And Bob Henderson, a Brit living in Cyprus, is a first rate engineer and a first rate guy.

The ICE filters are junk, and ICE is out of business. The Dunestars are a bit better, but still fail more than they should. Bob measured several of the 4O3A filters, and they are in the report.
