You looking for a cheapy one like a lyman, a kit that you build yourself, or one thats fully together thats of high quality andis gonna cost a pair ammount.
cheapy lymans can be got at most hunting stores, la barons.
kits can be got from Track of the wolf (its in the states), Pecatonica river (us) and for one up here Clark Industries he is in ontario and been building kits for a number of years, very nice rifles has a webpage google him. im not sure if he will build it for you or not.
i also think you can get prebuilts from track.
