There are plenty of them around and they go for a lot less than they are worth on ebay.

I know it's only a cheapo lens but I'm a VERY tight Scot so it has to be right

It may be normal though, so if it takes good pictures why return it? If the price was low, it could be worth keeping.

When I look through the view finder to focus ,the wobble is quite pronounced and it just feels like end is going to fall off .

That may be a little less than normal and a bit more worrying....

That looks good and on the K20D no sign of purple/green fringing (CA). I was trying the lens on my K-5 yesterday and it does suffer from CA on that body. Zoner has a CA correction tool which lets you select purple/green fringing with a dropper and remove it. It also lets you mask the area to change so that you don't change any other greens etc.
This is a crop of the corrected Wainright bottle which suffered from CA (at f/8 ). I took the same shot with the Pentax FA 50mm f/2.8 Macro and couldn't tell the difference apart from no CA.
