Southern Dunes and Victoria Hills would both be good choices in my book, although they are opposite ends of Orlando (SD way to the southwest and VH way to the northeast in Deland).
I thought Timacuan was a good course - I've only played it once, though. I played El Campeon a number of years ago and remember it being a fine, classic course - it would be a good choice as well, but it's north of Orlando. They have another 18 at Mission Inn, but I've not played it.
I thought Legacy at Alaqua Lake was very average.
I go with a group every spring, and Shingle Creek has become our departure day course because it's pretty close to the condos where we stay and it's very convenient to the airport. It's OK - it has that CCFAD/target golf thing going on.
If you're into tournament courses, there's always Bay Hill and Orange County National (Panther Lakes & Crooked Cat), the site of the recent PGA Tour Qualifying School Finals.
Other lesser know courses I've liked include Diamond Player's Club (I know, sounds like a strip joint), Legends, and Highlands Reserve. These are all in the Clermont area - an area that has pretty unique topography for central Florida. There is a lot more elevation change to these courses - very different from the typical, carved out of a swamp Florida course.
