My husband and I also agonized about whether to invest the money for the hammock, but we reasoned that the money we saved by co-sleeping and not buying a crib would go toward the hammock. At first, I was worried that we'd never use it because he wouldn't sleep anywhere but in my arms or someone's arms. but now that he's a little older, I'm so glad to have it because it gives me a chance to put him down during the day, even for just an hour at a time (though I need to check him and bounce him every so often). that's long enough to cook dinner or get something to eat myself
If you find the info email address on the site, the inventor is very responsive to email inquiries, and I recall he was trying to arrange a distributor in the US. You can try to find out whether that's happened yet, and it wouldn't hurt to ask if he is running any specials on shipping, as he had been offering discounted shipping for several months. some alternatives are the trading post and ebay-- right after we bought ours, one came up for sale on ebay, although it's hard to tell when they will come up. you might want to put an ISO on the TP. everything is washable, so i don't think buying used is a problem...
I will say that the hammock looks better in person than the photos on the site. At first I thought it looked a little floppy and odd. But it's very well-constructed and sturdy... the steel tubes
account for the high shipping costs. It may sound silly, but I was worried that it would look too weird in our nursery. But I really like the no-frills blue hammock we bought, and several friends have asked about it since. At the moment, we have it in my husband's study next to his desk so that while reading he can bounce the baby when ds starts to fuss.
If you do buy it, you may want to order an extra fitted sheet. Let me know if you have other qu's and good luck!
