I just purchased my first espresso machine (Decent de1pro) and need a new grinder asap. I have a Zerno Z2 on order but that won't be here until September. I was going to try and get by with my Fellow Ode 2 with ssp mp burrs but it doesn't have the adjustment required to dial in the coffee and I don't think it will last until September grinding espresso. I am looking at the key and A68 to hold me over. I'm looking for a grinder that will be different than the z2 so I can still use it when the z2 arrives to mix things up. I drink light to medium roast coffees and was wondering if anyone had a comparison between cups between these 2 grinders. I'm leaning towards the key for its versatility but looking for input and possible other recommendations before I purchase.

I'm looking to buy my first espresso machine after making pour over for 15ish years. I will primarily be brewing light roast coffee and possibly medium as well. I am definitely chasing complex espresso shots and likely won't be brewing dark roast at all. The features of the decent have me leaning towards it but the meticulous seems tempting with similar features minus the ability to change temp as quickly as the decent. The ecm is obviously a solid machine but with flow control being the only option, it won't be as versatile with options for tinkering with recipes like the other 2 machines. I can take or leave the steam wand and my priority is compact size, fast heating times and ability to tinker with recipes. Does anyone have any advice deciding between these machines or possibly any others under 5kish that could be better?
