Disposable Columns

I've been making home-made affinity columns by putting some glass wool at
the bottom of a disposable 20ml syringe and pouring the sepharose in on
top.  It works, but is a bit unreliable; sometimes the glass wool allows
resin to leak out, other times there's too much glass wool and the drip
rate is very slow.

Has anybody got any better methods for keeping the resin in, or can you
buy cheap plastic columns with a filter already in the bottom (which would
be ideal)?

Thanks in advance,
