I found them on Amazon too, but... very big or expensive. I basically just need a filtering flask and have/can jank the rest. I was just looking for an in person retailer because.... I like looking?

Sciplus.com has a hand pump vacuum and the flask (I have a food grade filter and funnels, tape is love), but.... I do so enjoy shopping in person.

Long story short: Thanks for the rec, I have bookmarked the filtr8 link and will buy there as soon as I have the spare change!
