Trusted Immersion Blender?

I'm just fine admitting I'm getting lazier in my old age. I make beans and salsa at least once a week, I'm tired of cleaning the blender between, looking for recommendations for solid immersion blender. Note: when I do my pinto beans theres whole chunks of garlic, onion, and at least 1 pepper in there cooked for at MINIMUM 6 hours. Hoping for a recommendation that can blend beans with additives without hassle. TIA
