Thanks for the info, on order as we speak. Comes with the color monitor, non flow thru sensors, which I want. I like the idea of being able to change the batteries, although the 510 last 5 years ,but you have to send them back to get replaced for a cost of 19.95. Seems like a no brainer to get the 507.
