The immersion vs. counterflow decision is one of the most discussed equipment choices in homebrewing, and the answer is less obvious than either camp usually admits. Both methods produce great beer when used correctly.

Building a DIY mash tun was the project that moved me from extract brewing to all-grain, and it cost less than $40 in parts.
The upgrade from plastic or glass to a stainless steel fermenter was the single biggest quality-of-life improvement I made in my homebrewing setup — more impactful than switching to all-grain, more impactful than building a fermentation chamber.
