I live a few minutes from Ethan's Glen. I like the homes and builders in the Gates at Ethan's Glen. I would be careful on lot selection - you don't want one that is near NC 50 (Creedmoor Road) or Hwy 98, as both receive a lot of traffic (including 18 wheelers) throughout the day and into the evenings.
The neighborhood is outside the Raleigh city limits in the Falls Lake watershed and will be on community water (provided by Aqua, NC) and septic, so the drought won't affect you as much as those who draw water from Falls Lake. Because you are in the watershed, there isn't much commercial businesses available. The closest grocery shopping is at Strickland/Creedmoor, about 7.5 miles away. But you will get larger (close to one acre) wooded lots, which I find to be worth it.
Commute to RTP is much better than those neighborhoods that are farther west, such as Bedford. To Northern RTP, near I-40, you are probably looking at a 20-25 minute commute each way during rush hour.
In your price range, there are other neighborhoods to look at as well in that section of North Raleigh. Check out
Parker Falls, which is is close in both distance and price to the Gates at Ethan's Glen. There is also Stonemoor, which is a little farther south off Norwood Road near Creedmoor Road. The homes there are a little bit more expensive than Ethan's Glen or Parker Falls, but are a good option if they are in your price range.
