Looking for advice on purchasing a quality Extender and Pump

As title says. There are many products available and I feel that quite a few are low quality and even potentially dangerous. Any tried and true products out there that a veteran could recommend?

If this matters for a recommendation, I have been doing the newbie routine for about 4 months and am currently 6.3” NBPEL in length. My flaccid length seems to vary quite a bit, which I do not understand, but it is anywhere from 2-4” non bone pressed.
