I suppose it depends how much you want to pay - £12 is very cheap and cheerful and probably too cheap to do the job TBH, but £200 is getting on for half the price of a second hand A410, and I would have thought overkill on such a rifle, so probably cheapish, but not crap is what your looking for?

I'll email you a picture of a few I have and don't use as most of my shooting is off a bag or a £300 bi pod for the more serious stuff.

Thanks
