First I would say to get both as both have pros and cons. I have both of them and personally I would pick the SRt-101 as I have tweak its shutter speed and is very accurate. I don't care for the meter in the 101 though. Even when new and with the correct kind of battery I don't think it's very accurate. I shoot the 101 sans meter as I don't really need a meter. If you do want a meter the meter in the XD-11 is far superior to that of the SRt-101.
