I kind of agree with the comments about the hassle of grinding for espresso with a hand grinder, and chose not to myself. However, in order to use a hand grinder for espresso it really needs to be one of the Made by Knock grinders or better, you won't get far with a cheap one designed for brewed coffee. But, I also don't think it is a waste, as you may want to try brewed coffee in the future, such as Aeropress, V60, maybe a cold brew in the summer. I bought an aergrind for exactly that. So it can do espresso, and will do brewed too. Definitely not a waste. But yes, hand grinding might get old if you're making a lot of espresso. I think the guys are just letting you know that the grinder is key to making a drinkable espresso at home, and that there is a strong possibility that the real waste will be if you buy an unsuitable grinder that turns out to just help you throw coffee down the sink and become sad and frustrated. You don't need to spend many hundreds, but I think something of the Mazzer Mini or Super Jolly level, (timer/doser model) will see you right until you have more budget. I had a Mini and it made good coffee, and is a reliable workhorse. Used super jollys are affordable too. I really only upgraded because I got fed up with the faff of a doser and having to dial in again after cleaning. I got a Eureka Zenith 65E which was a small step up in terms of grind quality and taste in the cup, but a lot nicer to use and live with. Those attributes are a luxury that can wait, but if you have to work within a tight budget, make sure what you buy will actually do what you want (make nice espresso) otherwise you really would be better off with an aergrind. I've never used a Graef so I can't offer my thoughts on that, but it's telling that so many are voicing their misgivings perhaps? Making good coffee at home needn't cost a fortune, but espresso does demand a fair initial investment.
