Several options:
1) Furling boom, about $8000. Just kidding!2) EZ-Jax(www.ezjax.com) Price seems OK.3) Have you looked at Mack Pack(www.macksails.com)? Under $600. and lots of testimonials on HOW.4) Personally I found regular lazy jacks from Sailnet to be suitable. About $150. and they easily retract out of the way when sailing and when putting on the sail cover. This on an H37C.
