I use an XLH1 and swear by it but I don’t think it is a good choice for home movies. The A1 is a third of the price, has a wider lens, is more robust, and has better ergonomics unless you are using the cam shouldermounted.
Todd is right about senn – they make quality products except the sennheiser MKE300 – that is a step down from the stock mic. I don’t think it’s even made by sennheiser.
