Hi,
Those € 75 are a steal for a dedicated, "plug, configure & play" solution which is very well supported, too.
The alternatives are ugly and much more costly under the bottom line:
• Write your own Joomla component.
• Purchase a "pro" Joomla form component which allows you database mapping and custom coding inside it. Then set it up and add your custom code.
Still not an alternative to the HikaMarket front edition component, but here is what I'm doing for shop admins who are allergic to the Joomla backend:
• Add a new admin user group and ACL specifically for them.
• Limit their backend access only to things they really need (e.g. certain HikaShop features, plus maybe few other backend functionality).
• Dumb down the product add/edit form to the absolute minimum by creating backend view overrides.
Also costs development time, and hence costs more than € 75, haha, but also gives them access to some (!) other things they need in the backend.
Bottom line, again: € 75 is dirt-cheap for what you seem to be needing, especially for a shop owner who's making revenue from his online shop and is saving time and trouble this way.
