No worries! FWIW, I was in the same situation a few years ago, with a high-dollar Britax that we loved, we brought it and used it until she outgrew it despite the legalities, but then found that we couldn't get rid of it as if didn't meet EU standards. (Couldn't bear to toss it, so we wound up hauling it back to the States one visit and letting a friend have it!)
Mothercare, Toys/BabiesRUs and Kiddiecare all have websites if you want to have a look at what you can get here.
