Looking for a port replicator

I am looking for a port replicator or docking system. I want to be able to plug my laptop into it and use my normal keyboard, monitor and mouse. It has to have dual video though. It will be a Dell inspiron latptop and Dell is no help in this case. Yes I know Dell sucks but it isn't for me it is for my boss. Any suggestions?

Dells do not suck. There are a great number of Dells with huge numbers of happy owners. Some of the cheap ones suck. And some with the wrong owners suck.
There are many port replicators, and many are sold on eBay and at Dell support sites.
But I would get my boss to buy a Dell that has a specific port replicator...
Or else I would learn how to burn my files to disk, or a backup external hard drive.
We need to know which Inspiron, age, operating system, memory, hard drive and such.
I would want to back up my data to an external hard drive, then tune up the existing install.

There is no Inspiron port replicator. Dell had nothing that would work for an Inspiron. I ended up going with a Toshiba Dynadock. Have any experience with those?
