Yes, the 290 BRU is at Hollister. I never thought it was that great, but I live within walking distance of it so I've never gone to another one. I think there is more green choices at BRU than at Target - they have 3 different brands of "eco-friendlier" disposable diapers (7th gen, Earth's Best, and Nature Babycare) while the Target in the same shopping center carries none.
We did thethingsiwant.com for Christmas this year... I have to say that my mom and my mil both had some problems with it and found it confusing. So maybe not a great option if you have a lot of older people invited. Plus a lot of people just go shopping the day of the shower, so I bet you'd end up with a lot of unwanted stuff that way.
I really like Nurtured Family too, but unless you want to register mostly for cloth diapers, their selection of other stuff in the store is not that big. http://www.nurturedfamily.com/
Another possibility is Bebe Verde http://www.bebeverde.com
, but I've never been there so I don't know the selection or if they do a registry.
