Isaac Farms is a really neat place, especially it you like to have a good selection of planters (a bit pricey, though), succulents and adeniums.
But yes, their website leaves much to be desired.
In full disclosure, Isaac Farms was the place I bought the double flower adenium that now is in pretty bad shape. I was a bit upset because it wasn't cheap, in fact, I paid more for it than any of my others, and now I'm just hoping it makes it. Of course, we all know that adeniums, as hardy as they seem, can be incredibly fickle plants.
The succulents we got there, on the other hand, are thriving and in very good condition.
