Tamarac is one of the weird little spots in west Lauderdale, you probably want to stay north of McNab/ Cypress Creek and west of University. There are some sketchy pockets mostly to the south and even in the eastern area but they pop up after you turn a corner from some nice places. Coral Springs and Coral Ridge roads which run north/south have a TON of apt complexes just to the north of Tamarac.
If you hit the apartment guide and have specific places in mind I can try to shake the cob webs off and give you any thoughts I can remember from the area. (I moved out of Coral Springs a couple of years ago but use to drive the route from where the Sawgrass makes the turn out there to the Executive Airport every day, so I went through there daily and shopped apts prior to moving into Coral Springs)(I usually looked at the cars in the parking lots to tell what the neighborhood was like)
In that area a 1 bed apt for less than about $1200 is going to be suspect.
