I found mine @ this address after being referred to it by another PA member:

They arrived dried, no holes and about 28" each...Cost me around $100 for the pair. If you want some I recommend calling and asking about availability in the 3' range. They are a husband and wife team and two of the nicest people I have ever ordered product from.
