Need Suggestions on Ebook Software

Presently I am using Corey Rudl's Ebook Pro. I love the security and features of it, however, I don't like that people have to download the software and then download the ebook. A lot of non-technical people are getting screwed up in trying to find the files and get to my ebook. Does anyone have any suggestions for a method of ebook fulfillment that has the IMC-level security but is more user friendly?

Better yet, I may also just put together another page on my website that walks the new customer through each step so that there is less to "figure out".

I have been looking at this over the past few days and was surprised to find that there isn't a wealth of info and/or software out there. I ended up with about 3, a $20 piece of software that was a $20 piece of software!!!!!! and the other 2 was the Ebook pro which seemed to be not forthcoming about the price until you got right to checkout, which I think was $197 and I also thought was excessive, so I more or less ended up with ebookeditpro from cybershare @ $97 which is (based on the options) what I'll go for, albeit they could do with a more comprehensive walk through or readme pdf. The ebook will be for finance/consumer related issues within the UK and has all the security features that your ebook should have, it will also, I'm sure, promote a professional appearance and finish.
Hope this helps

Apologies, forget my previous recommendation of ebookeditpro, dont go there. I was in the process of requesting support from them when I posted. I've not heard anything from them after 2 requests and 5 days. Fortunately I didn't purchase. However I have now purchased from ebookcompiler.com. This has everything you need and is very competitively priced at $49.95.
