Vinyl Collections - Where Does it End

Obviously like most collectible items unless you have a plan it can get out of hand, do you collect imports, limited editions, coloured, re-releases, boxed sets etc etc or do you just stick to main release only.

Aussie Floyd and Shine on Live

In the case of Floyd I have pretty much stuck with the original releases where possible with no duplications and only UK, except on the singles where I have diversified onto imports too. I would be interested to know where you draw the line with your collections or whether anything goes!.
