If it was me, I'd sure risk the $40 for 4 lines worth of HPEC. I have 
a Digium card so it was free, but I put up with a year of messing 
with the other software echo cans before HPEC was released and the 
day I got it working was the last day I ever heard echo and the last 
day my wife ever complained about it. OSLEC is also supposed to be 
good, but HPEC is easy and it works. Might work good enough you can 
stop buying hardware echo solutions for small installations.
