Anyone want to loan out their Ergo for a weekend?

Just wondering if any moms out there have LOs who have outgrown their Ergo (or similar) carrier and would be willing to loan theirs to me for next weekend. I have a Bjorn and we were planning on bringing it to NYC but I'm interested in trying another carrier because I find the Bjorn to be a little bit of a strain on my back after a while and I'd like to use the carrier more than the stroller while we're walking around the city. My friend swears by her Ergo but she needs hers. I don't want to buy one in case LO doesn't like it for some reason, although I'm sure she'll be fine. I promise I'll keep it in good condition and return it promptly, washed and everything. I can come to you! If you're looking to get rid of one, I very likely would be willing to buy it from you if it passes her "test!" Oh, and we have a Moby but I find DD is a little too big for that nowadays.
