The current Lewmar for a mid-size boat. Fine if you already have Lewmar controls; otherwise Sleipner is cheaper for the thrust.

Quick BTQ 140-30 Bow Thruster
#7 in Under 45 kgfFull review
A small Italian thruster for a boat of about 7 to 9 m. At the only Amazon price found it is poor value next to a Sleipner SE30.
