???I was wondering what do other fans like when collecting sets?

I started off just getting the original sets of things like furniture or market stall or even the castle. But when I got several different castles I just itched to see what different designs I could build - always bigger and better.
I then started looking at totally different sets to see if I could nick bits out of them to mix in with my first set, like making a market stall for pots and pans by using items from the kitchen sets.
Now I use anything I can find but I don't really customise the individual piece's (mainly because I'm no good at it!) only do mixed sets.
But at heart I think personally for my own collections I just love to see what I can do with original parts, mix and matching things to improve on my displays. I dont know i'm in two minds about it,

the victorian sets look pretty cool with extras in but I'm not sure I mix stuff with my Palace.
So if your talented enough to be able to do anything what would you do? And should you do anything, can Playmobil be customised too far?
I'm sure its been asked before but being new I'd love to get peoples opinions, I hope no one minds
