Those times seem high to me.  I have a 1.5/768 ADSL circuit and I routinely
see 13-15ms to my 1st IP hop and 15-18 to the upstream handoff.  I'm
14.5Kft from my CO and my IP is backhauled to SFO from SJC.  Here are a few
examples:

When I switched from 1600/384 to 3000/768 dsl, download speed went up to
very nearly the promised 3Mbps, but latency to the first hop went from
14 ms to 26 ms.

Now I have FTTH, and first-hop latency is 3 ms (acedsl.com, Verizon
reseller, good guys).
