Your most affordable option is to connect a shelter directly to the house ... but sometimes there just simply isn't enough height, so we have a number of great bracket options, including stainless steel and powder coated variants, and we probably use them about 40% of the time.
One secret benefit, which is often not thought about, is brackets create better ventilation, which is a really good thing for December through to March.
Be aware also that flashings - if added - will however then generally reduce ventilation!
