Very nice Mart. You and I have much in common. Once I get something into my head, I usually take the plunge. When it comes to drum gear, it's never enough, there's always that something else I need / want.
There will come a time when you'll have to sneak new toys into the house.
Here's one trick I've learned. Buy yourself the biggest, cheapest used cymbal you can find, and lean it up against a wall in your drum room. It's not meant to be played, but rather hide nice cymbals you may find along the way. These then subtlety make it onto your kit. If the wife asks, you just say " oh, I've had this for a while dear ".
Remember, it's never enough.
Cheers
