I've used dealextreme. If you're looking for cheap stuff, that will last you a short period, it's OK. For most cheap things, you have no guarantee you'll get what it's shown on the pictures (example you order solder wick and they'll send you another brand, and they say it's functionally equivalent so they don't care)
Lately, they also added some good items, like real Uni-T or Rigol hardware ... which are both decent brands. There's also resistor packs and capacitors and other small dyi things. For stuff like resistors, it's hard for them to go wrong, but I've seen plenty of fake capacitors or obvious old stock mixed with new or fake stock.
Recently, I've ordered stuff from DinoDirect.com , an LR meter and an infrared temperature gun, both Uni-T. They're genuine, package arrived in the standard (for my country) 30 days. At a brief look, it seems DinoDirect has less obvious fakes but otherwise there's a mix of no-name Chinese stuff and some better known brands.
I may use it more often, simply because they constantly have coupons like $17 off for a $75 order or 20% off a $120 order, stuff like that. I basically got my LR meter for free after applying the coupon and the prices are pretty much the same as the eBay prices otherwise.
Both list the packages as gifts or something of very low value, like $5 but I'm lucky the customs guy at the post office is pretty lax and doesn't care about what seems to be small value items. In theory, he would have to charge me customs fees for stuff over 25$ or somewhere around that value, but he probably thinks it's not worth 10-15$ of his time to collect 1-3$ in fees from me.
