Hi, I know this will vary, but I'm looking for a ballpark estimate. I have an opportunity to do a 3-day hook up to a CGMS thru our clinic (Dean). I'm not buying the unit, just taking it on a test drive Anybody done this, and about what did it cost before insurance? Am trying to decide if should do it now and later, or if I'll be able to do it once I might wait a little. THANKS!!!!
