How you clean up your sequencing reactions depends on your chemistry(big
dyes or rhodamines), number of samples and how close you want to get to
your primer.  Most Ethanol or isopropanol percipitations (cheapest) do
give some dye blobs at the beginning(can be improved with practice and
some tweaking).  We use CentriSep columns from princton separations

expensive ~$2.30 ea).  There are some cheaper sephadex G50 columns out

There are some options for doing 96well plates too.  
Check out ABI web page for some options and protocols
