Here's a link to the page that lists them.

I have another project in mind that this unit would work well for so I bought a second one for that project the beginning of the week. The seller had three left so I ordered one at $89. I checked this morning and that seller appears to be sold out. There is another seller that has a couple of the 6 port units listed but for $45 more. .

Anyway I hope this helps.
