The best, cheapest and most enjoyable way of expanding your collection (or
even starting your collection) of Pink Floyd and Solo live material is
through tape/CD-R trading.
Brian Davis created the Tape Trader's bible, which explains this all much
better than we could ever hope to do. The Tape Traders bible can be found

A weed is an alternative method of spreading a recording fast through a
large number of people, without having the overhead of making a tree
structure. Basically the person starting the weed ships a copy of the
recording to N people (for free, there is no trade involved) those N people
promise to do the same. So they announce on Echoes that they are weeding,
and will ship a free copy to the first N people who respond. Those N people
in turn will offer free copies to the first N people and so on and so on.
