I have only had two rechargeables, but I find I like the battery toys better overall. I don't like purchasing batteries so much and the best toys drain them fast. However, I don't like to plan which toy I will use a day or two in advance, as the rechargeable toys I tried required. Until they come up with a bevy of rechargables which are friendly for quick charges, I will keep purchasing batteries.
How do you feel about having to buy batteries, keeping them on hand, maybe having to keep a selection (AA, AAA, N, C, etc)? Do you shell out for rechargeable toys?
All my toys are battery charged. We already have a ton of rechargeable batteries for our Wii remotes and other various devices so it's not much of a hassle. There's usually a few in a charger somewhere around the house.
