I have a friend whose daughter loved hers, and she passed along an ad on Craigslist when she saw one for sale. I have to say - it's pretty impressive. It was maybe a little dirtier than I would have liked (I couldn't really tell until I got it outside - the seller's house was dirty, too), but I bought it for half the retail value, all the parts and electronics work, and there wasn't anything about it that couldn't be fixed with a good scrub and Lysol-ing. It's not like our baby isn't going to get it messy anyway. We plan to keep it downstairs once he gets big enough to use it, I think it will be great to put him in when I need my hands free to cook dinner or fold clothes.
I've been checking Craigslist every once in awhile, but I need to get on it more regularly. There was an ad for a swing I'm interested in, too, but by the time I e-mailed about it, it was already spoken for. I can see how buying baby stuff can be addictive. Next weekend we're going to Ikea for furniture!
