I think a little more information might help.
What is the water clarity where you are diving? 5-10ft, 10-20,20-40, 40+?(very important for sizing a gun)
What is your target species? Im a virgin to freshwater spearing but I have heard that those big carp need some punch!
Do you like a rear handle? midhandle?
When anyone asks about a good gun and have a price restriction the first brand I mention is Hammer Head Evolution. They are high quality guns with affordable prices. They are set up with an open muzzle so you have the option of powering up with a second band. it looks as if you might be in Palau? if so shipping is probably going to be a determining factor.
Also Rabtech, Rob Allen, Omer, Beuchat, all these manufacturers have affordable guns.
Well... back on topic, I think the first thing you need to find out is what size of gun your going to need. Shorter guns (55cm-75cm) are great for lower vis. The clearer the water gets the longer your gun needs to be (75cm-110cm). I dive in hawaii where the water is typically 40-100ft of visibility. Most people get jealous when I say that but you must realize that clear water adds a lot more to the spearing equation. you have a lot harder time getting close to fish in clear water. I use a 110cm riffe and would not go smaller than that. In fact there are many occasions that I wish I had a longer gun.
Hope this helps a bit. Maybe Whopperhead and his boys will chime in. They seem to be the freshwater experts!
