Herman- You would be hard pressed to find a new Channel Bank for under 
$1000US. On the second hand market (see Ebay) you can normally find good 
deals on used units sometimes for $500 or less as mentioned before. A 
strategy you could consider is buying used units along with a couple of 
spares on hand to cover yourself in the event of a hardware fault. They 
are fairly simple to swap out though obviously you will have some 
downtime.. For new CBs I would recommend the Rhinos. If you are willing 
to buy used items you will find good pricing on Adtran 750s. These are 
very solid devices. We use them extensibly in large analog rollouts and 
find them very solid and Asterisk friendly, even with used units.

Good luck.
