MY HUSBAND IS BUYING ME A KITCHENAID BUT I CANNOT DECIDE WHICH ONE TO BUY!!!!

People of reddit!! I really want a KitchenAid for my birthday, but I am at a loss as to which to buy. I bake a good amount (cookies, cakes, and bread), so I think I want the lift bowl. I also think I want the 7qt bowl because, while it's just me and my husband at home I do bake a lot for other people. HOWEVER, I keep seeing that it may not be a good idea to buy newer ones. Is this true? Am I better off just getting an older/used one off of FB marketplace even if it isn't a lift bowl?

Help a girl out please!
