Well I got my MX2424 up and running with the 72GB drive and now I am at a crossroads. I now have as much invested in the MX2424 as I do in my Alesis HD24 (non-XR). I have had the HD24 for years with nothing but great service. I need to sell one, but I cant decide. I have the MX2424's remote as well and it records up to 96K which the HD24 doesn't. I probably could get a little more with the HD24, but its been noting but good to me..
