Ok, so I have little or no footing in this conversation, but recently two locum guys (one in anes. and one in rads) both got permanent positions at the hospital near me. They came there to do a little stent, liked it, and wound up signing on. So, extrapolating from that very limited amount of data it seems that it has no bearing to a very slight advantage depending on your career goals. Of course, this is a small midwest town, so it isn't exactly a "competitive" position....but it pays well.
