$40's not bad, they're great boards...but if your current one gets the job done theres no real reason to change it. the gun wont shoot any different, you might get a little more adjustability and some added firing modes, but thats about it.
do you have the older rail with the plastic feedneck and back cap? you might want to change those, or at least the feedneck. the plastic back cap will last just fine as long as you dont over-tighten it. an on/off asa is also pretty convenient if you dont have one already.
If you want to upgrade maybe you can even save a little bit more money, sell your current gun, and go with a higher end gun.
