Interesting. I had looked at Mikeboy's site, along with weaknees and several others. I was leaning towards ReplayTV.us because they had the most information about the various drives they used. I had passed on Mikeboy's because the site had almost no info on the drives used, just some photos where all you can see is the manufacturer's name, but not the model or any feature descriptions. However, all these endorsements will make me take another look at Mikeboy's site.
Thanks for the info. If anyone else has any comments I'd appreciate hearing them.
