Hi Seraphim,
Yes, Mppt is a dc to dc converter but also seeks the optimum "power point" of the panel.
Yes, I'd consider the Rogue controller as it is "state of the art" and just released. It has battery voltage sense wires. It is a similar price. If you do decided on Tristar instead get the 60 amp version as it is more efficient than the 45 amp version.

Read a good description of what the mppt controller does - basically a dc to dc converter - and I think that's the way I'll go. The Tristar seems more than adequate, and it has a heat probe. It also permits custom setting of the various levels etween charging modes, so it can be set to the battery manufacturers specs. Do you have any other suggestions for controllers?
