I got a cheap bike - a basically brand new bike that someone had initially gotten from Bikes Direct. I am pretty sure it has one of those cheap Chin Huar bottom brackets. And I've read about several CH BB failures. At least one resulted in injuries - the BB broke and a pedal fell off and the guy ended up on the ground.

I've already had a cheap bike's rear axle snap on me - and if things were slightly different that day I might not be here right now.

So - I know the crank is a "Lasco FR670." Does anyone know what sort of bottom bracket this accepts? I am pretty sure that the BB is a square taper type. How can I make sure? What sort of after market bottom bracket may I use? The drive train is a 8 speed Sora/Claris mix. The width of the BB also appears to be on the low side of 70 mm (or in other words, 68mm). So will any 68mm square taper BB work with the existing crank?
