I can honestly say I have been lucky and could use the word cheap but really it would be wise and lucky. My current Hybrid Trailer I got from my uncle for $1. cheap no lucky. WDH had a good system for $100. but found a Equalizer hitch for $75. on Craig's list that was $675. Wise to shop and look that was a year after the first WDH. As for most stuff you can find at Camping world can also be found at walmart or online for much less, again wise shopping not going cheap. Or how about that campfire in a can, $129 on sale at CW found it online from walmart different brand but works the same $65. So all and all I think you can save some $$$ if you shop around and don't just jump unless you have to.
