So based on the reviews I've read I plan to get a Quick Hitch from Harbor Freight and save the $200 or so off the JD version. I thought I had read that it was better to get the bushings from TSC or a similar ag supply. Well I went on their website today and the kit for just the two bushings (does not appear to include the top link bushing) was $32.99. My JD dealer had the whole kit (including the top link bushing) for $29.99. Am I missing something?
