Hello to all,
I've spent some time over the past few days looking around the site. I'm impressed with the members, all of whom seem very bright, witty and devoted to Playmobil. Thanks for the site, and for allowing me to come aboard.
My husband is very tolerant of my Playmobil habit. Really, let's face it, he's an enabler. Our daughter is my cohort. We have a great time searching the city for new items. I hope she never reaches a point at which she feels she's too cool, or too old, or some other devastating deviation. So far, so good. Fingers crossed. 
We're collecting various themes, but I'd say most of our sets are modern/city. 
Our larger sets:
#5300 Victorian Mansion (this was also our first)
#3185 Airport
#4324 School
#4279 Suburban House
#3240 Zoo
We have many other sets as well, but as I said these are the biggies.
My most recent acquisition was today on ebay. I purchased the #3165 police station and the #3162 getaway car. 
The set I have to talk myself out of most often is the #4404 Hospital. How I'd love to build that! I know I'll have to get it eventually, but for now I'm convincing myself that it's too expensive, too big, and a little depressing. We'll see how long this can last! When I do finally order it, I know I won't be happy until I acquire all companion sets, and every obscure medical related set that Playmobil has ever made!
The set I'm most eagerly anticipating is the #5302 Mansion. How can I be expected to wait until August? I tell myself that once I get the #5302 (and, of course, all its bells and whistles!), I'll be content. I won't buy another set for the remainder of 2011! Maybe even longer! Well, excepting a small special or two. Or, if I see anything in a close-out shop. After all, we must all be flexible!
