If lattitude is important, Kodak Gold 100 or 200 depending on what you can still get your hands on. I just shoot at box speed for pretty decent results. It is a consumer film so try to find fresh stock and it will be a little saturated, but for fall colors it does a great job.
I also like Fuji Superia 400 shot at ISO200.
Barring that, Ektar is another real good option. I use it but find it a little less forgiving when it comes time to scan. Exposure in the camera is important or scanning colors can be off. Though I find that my Plustek does a slightly better job than my Epson.
Also, using a warming filter can help but I find that it works a bit too well for my tastes.
