C.,
I have a double stroller I've been looking to sell. I have two boys (now 3.5 and 2 yrs.)
I bought the Graco DuoGlider in the Metropolitan pattern. Very sharp black/gray, sun visors, 5 pt harness, elevated rear seat, fits any Graco infant carseat, cupholder/tray for parents and first seat (removable), and an extra large basket which is easy to reach and holds a lot.
My kids loved it, although I didn't use it for more than 6 months. Once my oldest decided he was "too big" to ride in a carriage he was all about the "me walk myself" so we went out and purchased an umbrella stroller for the little one.
I spent $200 for my double stroller. It was quite an extravagant purchase and I wish I could have gotten more use out of it, however, it was a lifesaver for the short time I did use it! As far as being lightweight, well they're all pretty cumbersome, but I never had a problem folding it up and getting it into my minivan. It also has a one hand fold which is great. It's in excellent condition. I'd sell it for $80.
Go to www.gracobaby.com and check it out. If you want more info or a picture of mine email me at ____@____.com and I'll give you my home number and we can chat more.
