I migrated 20 domains in an hour or so. Excellent.
20i reseller filled a big gap for me when I experienced poor service from another reseller provider which I had been with for many years. Free SSL is available, great control panel, and (important) support that is responsive and effective. Migration of sites from the other provider was remarkably easy using the 20i migration tools - even pulled over all email accounts for a seamless IMAP experience. I would like to see a few more install scripts for other packages available, but its a minor detail. I am very happy I moved to 20i
