Milhouse couldent be more right!!!
I make it a point not to insult any gun manufacturer, as there are a lot of companies that i like. I however do not like a single thing about JBL guns. I have a JBL Carbine and since i don't scuba dive i hate the thing. I'm sure there okay (somewhat) for scuba divers. There shiney (a good thing i guess.. and the only one)lol. They don't float. There not neutraly boyant and there louder then an atom bomb when you fire them. There under powered for the shaft they use and ... i can go on..
I have a RIFFE Hawaiian Teak gun, a JBL Carbine and a Rabitech Stealth. I'v used Omer guns and a few other compaies. All are great.
Where do you hunt and what will you be using it for?
For your budget a good gun would be any of the euro guns really OMER (always great gear and guns) Sporasub (Good guns and good prices) If price is the main factor and you rstarting out, check out the Cressi Comanchie at
www.spearfishinggear.com (good gun, great price i order a lot off of spearfishinggear, tell Matt there your situation and he'll do anything in his power to help you. Great guy. Wongs and Aimrite are great guns!, very expensive, but considering the lifetime warenty, well worth the price) Riffe is a very good gun like you said but not always the answer. There versatile and great but pricey. If you can check out the Rabitech or Rob Allen guns (I'm partial to the Rabitech) i think it's a great gun and a great price. It tracks like a dream, DEADLY accurate and versatile. You won't be dissapointed. check out
www.sumora.com, they have a lot of railgun info on the site. or PM EEZerik here in the forums. He's the Rep.
Check out the Rabitech, OMER, Cressi, Sporasub, Picasso, Rob Allen and Wong\aimrite guns. You can't really go wrong with either one. In the end it comes down to what is best for you and your needs personally. Everyone is different. You can't go wrong with any of those brands really, especially if you want to stay cheap.
You will however probly more likley then not regret a JBL.. BIg Time. You'll use it for a while. Kill a few fish and want something else right after. All that money down the drain and nobody really wants to buy them used. There cheap, but you'll save money not buying one.. trust me. We'v all had our "JBL Times" though... i think everyone in here has had one at one point and will tell you the same thing.
