ER to Cardiac Stepdown?

Hello all. Just wanting advice or anyone's two cents. While I was in school, I precepted on a Cardiac Stepdown Unit and loved it! Pt's consisted of sheath pulls, post-MI, POD #1 CABG, etc. The manager did not have a new grad position available when I graduated so I took a Nurse Resident/RN position at a Level I Trauma center in the ER. I have finished my residency and have been working about 8 months in total (since being out of school). I recently emailed the manager from the Cardiac Stepdown Unit looking for PRN work. She only has FT available which she offered to me contingent upon interview. So now I am trying to decide whether I want to leave my current FT for this FT position. My ultimate goal is to work in the CVICU so in my mind, a cardiac stepdown unit would be perfect in getting there after solid experience. Or I could hold out and wait for an actual CVICU position to open up and apply w/ ER experience only. (I don't know of any at this time). Anyone switch jobs before their first year was complete?
