Fresenius Dialysis Advice on taking the job

I have a situation I need to explain and I hope I can get some much needed advice!!! I graduated nursing school in May 2008. I got my license in March 2009, I had two unsuccessful attempts at the NCLEX, but that doesn't matter now, I am now a registered nurse!! I have had a home care case taking care of a brain injured patient for a year and a half. He has a trach and G/J tube, so it's not a very complicated case. I understand and consider myself a "new " nurse. I had a job interview at Fresenius two weeks ago and the manager hired me on the spot. It took them a while to get back to me with some shadowing opportunities on the acute care unit at our local hospital. I shadowed today and by the time I got home I have a job offer with the pay rate included. I am in upstate New York and the hospitals here start new RN's anywhere from $21.50 - $23.00 per hour. This company wants to start me at $20.38 hr. I an undecided on this rate, I feel they should be a little bit more competitive with the hospitals. Any advice? Should I hold out and see what else comes along? Anything good or bad anyone can ad regarding this company? I thought I saw a post on here that said Fresenius starts you out at $4.00 more than the hospitals do? That's not the case here. Any suggestions would be greatly appreciated. Thank you!!!
