If you like the tone in that youtube clip, by all means build or buy a Rocket. You won't be disappointed. A Dumble-style amp probably wouldn't do it for you.
If you want a little more versatility, the OTS is probably a pretty decent amp. Maybe even spring for the HRM or Bluesmaster versions.
However, if you need an amp that's custom voiced to your tastes and playing style, you really only have two alternatives...learn to mod (or build) your own amps OR pay a premium to have an experienced builder craft one for you. There are at least half a dozen builders on this forum who would PM you their prices and terms. Just ask and I'm sure you'll get a few responses. Be prepared to wait since they all have backlogs.
Hope this helps.
In the interest of complete disclosure, Moss at BrownNote is a very good friend of mine and we've built more than a few amps together. However, Moss would never agree to build you a D'Lite if you were looking for Rocket tone.
