"bin there, dun that" using Digiboard PortServer II's. I wasn't all too
happy with performance, though.... And the price is pretty outrageous
compared to a Boca BB2016.
Digiboard PS2 - 16 port = $2000 (Canadian)
Boca BB2016 - 16 port = $300
Of course, for an extra $800 per 16, you can upgrade the PS2 to max of 64
ports.... But for about $800, I can buy "el-cheapo" used PC's, drop a
BB2016 into them, install Linux, and spend less money than the PS2's....
If you ask me, the Boca boards are a good deal all around....
But, if you want to buy Digiboard PS2's, I've got two "like new" one's
sitting right here that I'd really like to "unload"....
