[R-390] Filters

Absolutely.

I've seen those come and go. The concept is great, but the market is 
very limited, hence the cost.

A savvy ham with the proper background could homebrew a very nice filter 
for a relatively cheap price. Soldering the hardware together would be a 
fairly easy weekend project, assuming you had a surface mount adapter 
board for the DSP chip. The software would take many weeks to write and 
even longer to debug.
