I'm trying to find a good price for a set of nipple pumps, since I want to buy the double connector with it. Vacutech and Fort Troff both have them for like 60-70 bucks (really? >_>). Also, what's the best sizing result. Fort Troff offers 1/2 inch and 5/8ths inch as their small sizes. Vacutech only offer 1/2 inch before they jump up to 3/4ths. I prefer eraser nipples, so I'm not looking for wide-area coverage. Between the two, which would give a more eraser-like effect. Logically, the 1/2inch takes up less extra skin but does that limit the shaping of a thick-ish pencil eraser type nipple?
