At that price I would recommend you to get Sony Erricson Neo V. It will also get a Ice Cream Sandwitch upgrade. The reason I would suggest this over Bada is that I donot think that going for Bada is a good choice in long run. Samsung mostly bundles Android with their main phones. Bada is no.2 there.
Also another great option would be Samsung Omnia W. Great Windows Phone 7.5 phone. Sleek and a smooth UI. If restrictions like no file transfer over bluetooth is not a problem it is a great phone to get
