There's a product called Hot Property that is simply amazing.   For a one time license fee of about $100 you can create a website that allows you to build a website to showcase homes for sale or rental.    Here's a snip from their website:

We spend our time studying online Real Estate Management System and talk to the people who really use them. Our products are developed based on these studies and feedbacks from users.

Why this is so amazing...

If you're thinking of a revamp for your website or are tired of paying high fees for something that isn't high quality... you must consider this product.

By the way, this is not a replacement or competition for MLS.   Hot Property is simply a "plug-in" that can be used in a website to give you the ability to showcase homes.   (Go visit their demo if you want to see what it looks like!)
