An inexpencive solution is loading your fragments on 0.6 % agarose gel and
then just elute your cut-out agarose pieces with a handmade Sephadex G50M
column. (fill a tip  with it and centrifuge). We use it all the time for
any kind of applications: prior to sequencing, ligation etc..
Hope this answers your question
