Looking to purchase chin-up / dip bar(s) for use in my apartment.

* Has anyone worked with one of the doorway models (Door Gym, etc.)?

* Is a permanent, stand-alone unit worth the cost / space?

Thoughts appreciated.

go to academy sports and outdoors they have a cool pull-up bar/ dip station combo... costs about 60 bucks but it works good for me

I bought a pullup kind of thing from a rock climbing gym it has big grips for your hands and littler ones for your fingers it can give you a good workout, i put it over a doorway it looks pretty cool
