Wix for the most part is great for someone trying to sell the pot holders they make or for someone with a niche market but other than that I'd either build a DNN site yourself (much more up to date modules) or just use ecrater.com.
My biggest complaint would be is that they nickel and dime you to death and place ads on pages that you will be working on most of the time causing slow load and delays in your work. They don't just put ads on the dash board they place them on pages like orders or other important pages so do not be in a hurry.
My other complaint is they are trying to reinvent the wheel. Their modules are so old fashioned or were developed by someone else so long ago there is no reason theirs don't work properly,...stuff like you would have seen when IBUYSPY was put out there by Microsoft they can't get right or don't even offer. Simple stuff like the abbreviation for states being populated, just seems like a bunch of not so bright people work there in my opinion.
It is better than nothing and if you don't have the skills or time it's a good temporary solution or if you could go to ecrater.com they've been around since IBUYSPY...
