Disappointed By PLR Sources... Seeking Opinions Now

Hey guys. I'm trying to find PLR or MRR ebooks that I can give away to readers of my blogs but have either found 1) really low quality sources or 2) decent quality stuff that's only articles. If need be, there is always the option of compiling the decent quality articles and turning those into ebooks but I'd rather not go that route if I don't have to.

Anyway, it would be great to hear your opinions of good sources. Since I have quite a few blogs (and am aiming to build more and more) I'm willing to pay to join a site, but I'd rather have opinions first before paying to join.

Here are the three PLR sources that I use often and which in my opinion have quality contents you can use or give away to readers of your blogs:
resell-rights-weekly.com
resellrightsmastery.com
plrwholesaler.com

There are many good PLR products already shared on this forum. Also, tricks to find PLR products for free .. use the search button to find this goldmine.

@xyberk - Thanks for that... will follow those links and have a look.
@sikandar - I've come across piles of stuff on the forum of varying quality. But I gave up on that route when I found myself editing the hell out of a few finds that applied to some of my niches.... not really worth it if in the end there's not really a time savings there.

I know that often PLR stuff floats around that's just spun content and I don't even mind that, but if I can find a more quality solution, that would be better.

I'd even considered outsourcing the writing, but that doesn't really make sense when there are so many quality sources out there. So it probably makes more sense to find those sources and put the money there instead, because the secondary benefit is the access to a larger amount of content overall.
