Need a solid shop plugin!

[Nuin]

I have been playing around with ChestShop and Vault, as well as Essentials' sign shops, yet I get problems with each. ChestShop works to an extent, but doesn't update the inventory until I try to place/move the item in question. Essentials works in a similar fashion but Buy signs don't work, only Sell signs.

Anyone have a decent plugin that they use on their SMP Tekkit Lite server that works? I am running BukkitForge at the moment, but I have a feeling that I will be moving to MCPC just to support my plugins (WorldEdit, WorldGuard, etc.). Thanks for any tips or recommendations!
