Luminosity Masks for Landscape HDR

Hello

I like landscape photography, and I would like to learn to make HDR images in photoshop using luminosity masks. I have started using Auto Exposure Bracketing on my photos to generate a range of exposure for each image, however I found lightroom's default HDR merge function to be disappointing.

Does anyone have tips for creating manual HDR in photoshop? I have seen some plugins or photoshop actions before that manually create luminosity masks that looked good. Otherwise I guess I would simply select the sky with a layer mask and replace the sky with one of the different exposures.

Any tips would be appreciated.
