I'm not sure if you would classify as toys as such...but it depends on what you are into.
You could invest in Paddles/Spanking implements, Riding Crops are quite fun for example.
Nipple clamps, I hear clover clamps are particularly good.
You could get some rope ties for your wrists and ankles.
I would say, what are your kinks? What do you want to get out of toys and approach things like that, would would you be excited to own?
What would you get the most use out of?
What could you buy that would be far superior to household objects?
Make a list and start fantasising how you would use these items, or how others would use them on you and start by buying the items that get you the most excited
