If you want just a charger (not charge/discharge) then you can't go wrong with a Pitbull. I liked it so much I bought 2!
For setups I would go with Hudy. There is a cheap metal copy made by integy but the original is still the best!!
Tools- Hudy again! Nice tools, just a bit pricey!
XXXs is not so popular in Hong Kong. There are too many 'other' cars available and it doesn't help with a distributer that ain't that good when it comes to spares!!
