For the most part, I'd agree. I've bought a number of templates there. However, many of them tend to be very opinionated, adding a lot of JavaScript and non-Bootstrap markup. You see a lot of the same features that feel "me too!" (for example, parallax sliders) Once you buy and start converting to your needs, you'll find that the files and directory structure may be a little jacked up (recently did a lot of the work with the Ace Admin theme, and found image directories inside of the css directory, even though it had a separate root images directory, and there was both "images" and "img" directories.. fun.
That has been my assessment as well. I once bought a theme there and ended up spending more time changing the code so the classes are similar to what Bootstrap uses.
That's why I am starting http://bootmystrap.com/ All changes in just one LESS file, using same classes as Bootstrap so if you do buy a theme it actually saves you time.
I've had that same experience. I bought a theme very niavely thinking that it would follow bootstrap conventions and would be easily modifiable. Instead, I've got a huge mess and I think I'm just going to throw it out. I've been looking for a site like yours, that actually respects LESS. I hope it takes off and will definitely be keeping an eye on it.
I agree. If you're building a site you're going to end up maintaining for a long time, you should be building it from the ground up yourself. These sites are great at inspiration though! Your site showcasing extremely barebones demos is great.
