From the standpoint of a site designer and one time member of many online pay sites, I have to say climaxcorner.com is the best I've seen so far. What you get for what you pay is a great value, and the navigation system between DVDs and their scenes can be done through a variety of filters so you find only exactly what themes or producers you want to download. climaxcorner.com
All the online porn sucks. All the store-bought or mail-ordered porn sucks. All the print porn sucks. Only the people who perform in it, produce it, distribute it, download or buy it are worth a shit.
I dunno shaun, i've been pretty impressed with DownloadPass.com ... they've got i think thousands of full size DVDs.. pay like 10 bux and unlimited downloads.. i've burned like 20 already
