Best ADSL2 filter for install at the NID?

[digitalbitstream]

I've hacked a stock DSL filter to sit at the NID, making a home run to the modem.

But what should I use? How can I get the best quality filter for installation at the NID, to maximise connection speed?

How would I tell if this one is good, for example:

Or

or

Maybe sonic should offer something to customers? Speed is sonic.net's Achilles' heel, except in islands near a CO.

The first one is out because it's ADSL1 only. There are some that look like that but are compatible with ADSL2+.

I have had good luck with the PS-32 from Wilcom:
