Nice work getting the fairy sets! They seem to be very popular, as I had trouble finding mine for retail a while back. I think they may be popular even beyond Playmobil enthusiasts, since they're sold out most places you look online. The Fairy with Fawn set in particular was a pain to track down for the normal price. (She's the blonde one)
I'm still looking for the pink Princess with the yellow unicorn. I don't want to encourage you to overspend, but the Beauty and the Beast Disney Princess set is a nice Princess set too. 
I can understand why the fairy sets are popular - they're really lovely. I lucked out & got 70401, 70402, 70403 & 70127 + the incomplete 6741 house set for £5 (+ postage) a couple of years ago, & then had to go buy 70400 new to complete the (then) fairy sets & figured WTH & go the bucket set too.
Is the Beauty & the Beast one you mentioned 71458 Belle's Tower? (It's sweet but not really my cuppa!) I do really want the new Tinkerbell set that is coming out though, & I'm trying not to look at the Winnie the Pooh sets because they are *adorable*.
