Anyone heard of centon cameras?

Hi all,

I recently picked up a cheap 35mm SLR (£19 GBP) centon k100 camera in almost new condition. With a 50mm and 70mm-210mm zoom. From what I've gathered it's a Chinese made camera made for Jessops. Uses a Pentax K mount. I can't seem to find much else apart from the user manual. I wonder if anyone on here as any experience or extra knowledge about these cameras. I know centon is far from any canon, Nikon or OM1 but it seems to be a reasonably made little SLR.
