Good GUI shop plugin?

[Nuper_Flund]

I'm looking for a good GUI shop plugin for my server.
I've looked everywhere for one and can't seem to find any I'm looking for..
I'm not looking to have one made for me but I am willing to pay for a good one that's already made.

I probably won't reply, but thank you for helping if you do!

ShopGUIPlus is the only good one on the market, as of right now.
If you want a free option, try GUIShop.
