Cool. Now I need something to make sure my wee wee gaming session doesn't come to premature end.

just what i needed to statisfy the little ones at home

Skip this and go for the batteries.

good but a little pricey.

Be very careful of these 3rd party chargers.
They can be fire hazards. Most are not even UL approved.
There is currently only one Nintendo approved Wii battery charger and it's made under the Nintendo License by Sanyo, currently not sold in the US yet. The Sanyo charger will charge the Wii remote with the silicone jacket on and has a space for the wrist strap too.

Until this hits the US market I'll probably buy Alkalines. (or a seperate AA charger)
You can buy a 48 pack of AA BJ's brand Alkalines at BJ's Wholesalers for $7.99. That's .17 cents per AA battery before tax.

...or $13.99 for a 36 pack of AA Duracell's from BJ's Wholesalers. Probably the same price or cheaper at Costco.
