90 or 100 centimeters euro, as said by the lads! It's the perfect all-rounder, not too big for reef hunting on small fish, not too small for stoning the big ones, compact and simple enough to be handled by a newby.
In the Usa you can find a good deal on the Omer Cayman alluminium: I suggest this gun as high value for relatevely low price.
Check the american online stores and you'll find many good deals. For instance, look at this site and drop a mail to the owner of the store, Jim: he's a great guy. Tell him you're from Deeper Blue and he'll surely be VERY nice to you.
