I'm looking for a Portal addon for CSS.

I don't want the Portal Gun. I'm aware of that portal and do not wish to use it for my server.

I'm looking for a portal like the one for L4D2. The L4D2 Portal is very easy to use. You just point to the ground and say !sm_p or !p once for the from portal then point somewhere else and say !p for the to portal.
The only CSS map that I remember playing on that has a very nice portal is the Walmart_v5 map. There is a portal in the center of the parking lot, that transports players and bots to a location inside or outside the Walmart store.
If there are some other CSS maps with built in portals please tell me the name of those maps.

I'd be happy just being able to place a portal on a map or maps if I can't get a portal that a player can spawn.

So, if anyone out there can point me to a portal addon that is current and not too buggy please let me know. Thank's DBD...
