Welcome!
My experience with DHs is not actually that they can't handle something like a snappied prefold and cover. It is more that they want a straightforward stash, with as much sameness as possible. I find that moms like to experiment and have a little of many different types of diapers whereas dads want to do the same thing every time, every change. My DH loved our prefolds and was really good with a jellyroll and snappi and a velcro cover. You know your DH best though of course
I encourage you to just keep researching and looking around for brands and styles you like. I would put away money slowly rather than stock up on diapers slowly. New and better ones come out all the time and once you've done your research and saved up your money, you can wait for big sales when you are pregnant and stock up then. That's my advice anyway. I know some ladies just can't help themselves esp when it comes to newborn fluff
Okay and I am writing a book here sorry, but my stash was all GMD prefolds and covers through newborn and small, then I got into GMD workhorse fitteds and Tinkle Traps prefold fitteds, and finally in size Large we are doing Bottombumpers AIOs, Flip covers with padfolded flats, and fitteds (mostly Motherease Sandys) with wool and fleece, and I occasionally fold a flat or use one of our few toddler size prefolds. My stash got very ADD on me but I enjoy the variety now (although my husband always goes straight for the Flips and flats).
