I'm going to give the Pek Supremo system a try. You might take a look
at it. I will post my thoughts on in after I've used it for a while.

I'm currently using the Metrokane hand pump (
http://www.metrokane.com/site_files/...er_vacuum.aspx ) which
I think is the best of the pumps. It creates a pretty impressive
vacuum in the bottle. I drink mostly cabs and merlots, and they appear
to last just fine for 3 days using this device.

I hope this helps.
