You tell 'em, Lewis!
There are Numerous excellent Hitches available for the wing. I have NO experience with the Elite, or the Add-on, but the four most recognized are the Bushtec, Kuryakyn, Dauntless, and Hitch-doc. HDL sells at least 2 of these and one or 2 others. The price range you found will put all of these into your budget.
I have the Kuryakyn on mine and am COMPLETELY satisfied with it. However, if I knew about the Bushtec when I was shopping for a Hitch, I would have gone that route.
All the major manufacturers use a minimum of 6 frame/subframe attachment points. Kuryakyn chose the rear highwaybars instead of the lower frame point for customer ease of installation. In my opinion, just as strong for almost all purposes.
Hitches like all other "what do you think of ..." queries will produce numerous responses, but it's what you think is the best overall for you.
Hope that helped you a little.
