hi. when i was a first time mom i wanted one too. i bought one that did not work and ended up renting one for a month (in the US). i would recommend not buying one b/c the cheaper one that's sold in baby stores don't work a lot of time.. but the ones that work will cost a lot more and once you hit 16-20wks you can feel your baby kick anyways you don't need it.
