The short answer

The SEESII AG0200S costs $16.99 more (29% more) than the CRAFTSMAN CMCG400B — $75.99 vs $59. For the extra money you get: a complete kit (everything you need in the box), a brushless motor, and variable speed.

Bottom line: if you'll use it often, the SEESII AG0200S is worth the $16.99. For occasional jobs around the house, the CRAFTSMAN CMCG400B does the work for less.
