well.. if u go for a brand new cocker, the only 1 really in that price range is the stock cocker, it is a very nice, efficiant marker,
but if u get a second hand cocker, u can probly get and Evolution or even a blade cocker. which r the best cockers u can get for the price, but just try before u buy m8, fire a few cockers.
have a look at
www.planeteclipse.com
www.smartpartseurope.co.uk
both with decent cockers, planet has a wider range tho,
