Inexpensive entry level gun?


I am a beginner spearfisher, I have used home made spears for fishing before, and I wanted to go up to the a higher level. I was looking into buying a speargun (my fist actually) and I don’t have the money for a top of the line gun,  also i would like a small gun maybe around the 17-20 inches long, what do you recommend?
