first timer try to buy used... who knows later find too troublesome  and give up...

fully auto is one press done.... but if fully auto why not those capsule ? generally fully auto quite pricey but easy to use. quality wise... depend on ppl la..those coffee lover usually avoid fully auto..

semi auto is depend if you have time and passion for it... cause it takes time for the whole process (from grind to espresso to latte to wash ur stuff) to get your nice cup of coffee...  quality wise...is good....

most ppl regret buying semi is the hassle..... they just want coffee... and simple to make...tats it... so depend on your liking

cool...since you're used to the cleaning up routine...then i too would go for better machines

so you're adding espresso to your coffee palate?... personally i don't want a grinder attached to my brewer for better/easier upgrade path, flexibility and reduce risk of one failure and the other out of service

also you probably know full automatic doesn't brew as well but the benefit is just press a button for instant coffee

i have no personal experience with any of the machines on your list...just wanna suggest maybe getting a good starter grinder, like the baratza sette or eureka mignon, then if maybe you want flexibility with milk drinks to get a hx or dual boiler machine for better steaming, if not then most sbdu machine is a good start...you can get a mignon grinder and china made gemilai machine for about $2.5k...or future proof and get an oscar for milk drinks [ my mrs 100% latte ]

p/s...imho try go for standard 58mm filter baskets for machines...

i think the only downside with fully auto is the ability to customize e.g grind size, time and temperature... its one press and done.... semi auto, generally requires you to tweak a bit with every new bean (if you are changing everytime). for me, i got my bean from online and offline and various roaster. so each time new bean i ll need to tweak the grind size to get the optimum output... will get it right eventually after one or 2 espresso...
from the way u explain...semi auto is minus off the hot water part. the rest remains the same. measure, grind, tamp and time the extract. i usually dose 18g and 36g output as close as possible in 30 seconds
online n offline. for me beanshipper, nisy, 103coffee, ppp, havent try perk though...

Harvey Norman will frequently have their Delonghi, Saeco and Breville representatives do demos of the equipment. I got a demo of the Delonghi Dinamica yesterday at Harvey Norman IOI City Mall during their Leap Day sale. All I can say is the latte felt off on many levels. Obviously I have no idea what beans was used although the milk was fresh. The cleaning routine looked a lot more involved than I expected. I recommend bringing your beans and doing a taste test.

My normal routine is using the Breville 920 dual boiler with a Eureka Mignon grinder with beans from Reframe, Fmarketing on shopee or Beanshipper.

If I had to choose between the options you listed, I'd go for the Brevilles because you have a bit more of the extra control as you have the option to dose and tamp yourself. Ideally the touch because it automates the milk steaming as well. But the recommendations others have made are very valid, you'll likely make a better cup with a semi auto and a good grinder

Good luck
