Hi Anthony,
As suggested, an idea for couple of 'K2 specific views' (templates) that could work with Avanti or any other K2 enabled template.

1. A product category listing page (i.e. real estate/property listing). Following examples provide an idea of what I mean.
Example 1:
www.findaproperty.com/searchresults.aspx?edid=00&salerent=0&areaid=0249&prt=1&abeds=1&bedrooms=04

Example 2:
www.sequencehome.co.uk/properties.asp?br=-1&cs=15&type=0&b=CHF&prop=100003&min=-1&max=-1&bed=4&Go.x=15&Go.y=13&Go=Go

2. A product detail page (i.e. individual property details)
Example 1:
www.findaproperty.com/displayprop.aspx?edid=00&salerent=0&pid=5539935

Example 2:
www.sequencehome.co.uk/detail.asp?type=0&src=property&cs=15&bs=CHF&br=-1&prop=100003&min=-1&max=-1&bed=4&page=1&id=CHF100983

The other option/request concerned a tutorial/how-to on the steps to be taken customising the default K2 category/item layouts.

All the best,
Mark
