Our Verdict
For most construction projects, the 20-30 tonne class (Cat 320, Komatsu PC200, Volvo EC220) offers the best balance of capability, transportability, and value. Mini excavators (1.5-6t) are the fastest-growing segment due to urbanization and landscaping demand — the Cat 305.5, Kubota KX057, and Bobcat E50 are the top sellers. If you're unsure, rent before you buy — it costs $200-800/day for most classes and helps you determine the exact size you need.
