Any info on Medical Center of Arlington

Good day to all Texas nurses!!!!!

I have a phone interview tomorrow with Medical Center of Arlington for there cardiac care unit that is opening soon. They are offering a sign on bonus which scares me during these economic times (why are they offering bonuses). Does anyone have any info on this facility? It is a Questcare Partners hospital. I am from Boston and know very little about Texas nursing. I know the pay is lower in Texas, but the cost of living may be lower also. (as I make $31/hr not counting diffs with 2 years experience). Any info would be greatly appreciated!!!!
