Get a ER RS135 at that shop that has midnight madness sales. Great skimmer, I've got one on my 120. Plus, it's build tough. My kids (that won't happen) could clean it and put it back into operation.
I've got a g3 mesh/gate mod on my 60 and it does a good job, but not as good as the ER. The G3 seems to be pretty flimsy in comparison.
