Well I just purchased an older Tri-Tronics 200/LS off the net for $150 and seems to work good. The one you mentioned should be very good as it has more whistels and bells then mine.
Reading some posts on these on another site I feel the Tri-Tronics is the better for battery life - warranty - trade in value ect.

Bird wing should help and don' t see a problem with getting him turned around. Pick a different area (shooting preserve birds?) for training so you don' t get a repeat.
