If money is an issue and you still want a wooden gun , my pick would be the Hawaii Skin Dive yookoji gun. The prices for the rear handle goes from 340 US (44 inches) to 370 (55 inches) , I think they are better then the riffe guns.
The 44 inches is a little smaller then a 90 cm euro gun (murky water only), for you may be the 50 or 55 inches. The come with two bands and shaft (9/32).

The price on the middle handle range from 380 usd (50 inches) to 400 usd (58 inches).

But if you want to go cheap you can get a sporasub black viper for less then 100 usd on the scuba store.
