Fish,
I'd seriously consider the Regal.
No, it's not "true" rotary but after having a Regal, a couple of Renzetti's and now a Snowbee-Waldron I'm of the opinion that true rotaries aren't absolutely necessary! Especially if you aren't stuck in your ways.
I tie lots (lots!) of those warmwater flies too and the Regal is superb for exactly that. You can still rotate your fly to get to all sides easily enough if you need to but I honestly don't think it's the most important option on a tool for your type of ties.
Jeremy.
