I've been wanting to begin to train MMA, but money is an obstacle.

I'd like to be able to do the MMA training at home, (so not the actually fighting part, just the techniques and conditioning aspects), but I don't want it to conflict with my weight training too much. (I know it will a bit)

Someone recommended "The Pit" DVDs to me. Does anyone have any experience with these? I have no equipment... So I'd have to stick to the BW stuff...

Any recommendations?
