We are in the same situation. I have looked at both Websmart by BCD and RPGSP by Profound Logic. Both offer good products, outstanding tech support and a free 30 trial of their products.
I decided to go with RPGsp because it seems to be geared more towards the RPG programmer with a limited knowledge of HTML. Plus, if I have any questions about how to do something, all I have to do is pick up the phone and they will talk me through it or, by using Goto meeting, connect to my machine and do it for me. All the while explaining what is being done. This way, I not only get an answer to my question, I also get a lesson in java script, html, or whatever else my question was about.
