You're only asking for entertainment purposes, right?
Juice decks are fun, but with pre-made decks, the quality is all over the place. Some mark them too dark, others too light. You also need to factor in the style of marks (not all juice decks mark the suit).
You could try to find the "juice" and make your own - but it's a tedious project and not a good solution if you don't want to put the time in to experiment. You'll waste a ton of cards in the process, so that's something else to think about.
I would suggest perhaps contacting the guy who owns that website, and see if he can offer a sample of his work. Perhaps he can send you a single card or something as a test?
The price on the site isn't bad. Some decks can cost twice that amount. If you feel like giving it a try, go for it. If you like it - let me know!
