Suggestions/Recommendations on a tonneau cover

[Big Racks]

I've sold my quad so am thinking of putting a tonneau cover on my '15 Toyota Tundra double cab (6.5' bed with rails). I've never owned one, but like the idea of it over a hard top canopy mostly for ease of removal, cost, etc...

What are some good ones? Pros and cons of one style over another (ie: tri-fold vs. 1 pc. w/hydraulic lift vs. soft roll up style)?

Seems to be a lot of different ones out there, and a wide price range on them. I'm thinking the clamp on might be the way to go so I don't have to drill my bed or rail. Looking for any suggestions or recommendations on what to look for and what to avoid, also what I can expect to pay approximately.

Thanks in advance,
