...if you scroll through the drop down list, it isn't sorting correctly. It should be in alphabetical order, but some values are appearing out of sequence. Maybe something to do with case or character set? To replicate the problem try searching for a Pyrahna Large Burn.
Also, it would be nice to have more filters, i.e. one for product type (Creek Boat, Playboat, OC1, Helmet, Paddle, Drytop, Camping, etc), then one for manufacturer (i.e. Jackson, Liquid Logic, Kokatat, NRS) and then one for product (i.e. Large Burn, Remix 79, Creek Gloves, etc.).
With this, it would be way cool if the filters worked in a hieracrchy where what you select in the first filter, limits the values available in the second filter, and so on. For example, if you select Product Type = Creek Boat, the Manufacturers drop down list gets populated by a group by query of all the values in the Manufacturer field in the records with 'Creek Boat' in the Product Type field.
It's kind of cumbersome to have to scroll through one huge list of product / manufacturer combinations. It's still a great resources, just some what if's.
