Stonecrest and Del Webb Spruce Creek call themselves gated communties, but I've driven to the gatehouse and said I'm going to the golf course and was let right in.
If you want to see a real gated community of homes in the $200K to $300K range. Drive about 75 minutes southwest of here to Spring Hill and to Timber Pines on US 19 or it's sister community 5 miles south, Heritage Pines on County Line Road. Tell the gate agent you want to go to the golf course, or to see a house for sale, or to visit someone, and they'll tell you, you can't come in. Unless you're with an approved Realtor or a resident has left your name on the guest list for that day, you don't get in.
