The ability to know the exact vacuum pressure and adjust it is definitely a huge advantage, and that pump is not that expensive. If the minimum pressure is not too high (at most 50 mmhg minimum pressure is what I’d personally want) and the cups have a circumference similar to NB or BB cups, please let us know, because I bet other people will be interested in buying it. I don’t want to underplay the importance of being able to choose the exact pressure. I agree, It can absolutely be worth paying more. It really depends on how confident someone is in there ability to determine different pressure ranges by feel alone. In order to that though, they need plenty of experience using a gauged pump of some kind. A gauged pump is always safer.
