Generally speaking, Edenfantasys carries excellent quality toys. There are some inexpensive options that Eden carries, but for the most part you don't have to look very hard at all to find some really nice stuff.
That seems to end in the "Douche and Enema" section. I know it's not the most romantic section, but all of the offerings are three-star and below. Most of them are either somewhat exotic (large, shaped nozzles or shower-setups) or look rather flimsy even in the pictures.
Why doesn't Eden get some good equipment? It doesn't have to be the large, ominous "fetish" equipment, just some good quality basic equipment. AveryDragon did a review of the StreemMaster, and that looks great for a shower-mounted system, add a good quality basic bulb and bag (and maybe a Higginson syringe) that will last, and it will look a lot more respectable. I know that most of this you can get in drugstores, but there you have the embarrassment factor, and I know you can get enema equipment elsewhere online, but then you don't have the Eden reviews.
However, I don't have much experience with wholesalers and markets and product laws, so I'm not sure what the reason why Eden does what they do is, but I'd be interested in finding out.
