The lab using ABI chemistries where I worked originally used qiagen spin
columns.  They worked ok, but we found the gibco columns cheaper and
also that they yielded higher and more consistantly .   

If you are going the do pcr sequencing , I think the protocols in a
previous post are very good.  We spent months perfecting them for the
lab. (because of the high cost of the ABI regents , we spend alot of
time in the development fine tuning of the protocols.)
