Yes, but it is below recommended performance for a tournament, as you would be at a disadvantage.

depends on what is wrong with it. if its just a simple leak down the barrel it could just need some oil or the cup seal replaced.
The Spyder RT is good, considering the price. I picked it up yesterday. I have just been playing around with it, because i have no CO2, but the rocking trigger is really nice and you can make it seem like it's on auto with it. The settings: 3 burst, 6 burst, and auto, are really good, but it sucks because you can't use them in parks. The only thing that you will need to upgrade is the feedneck, which sucks because it adds like 2 or 3 inches to the barrel. I haven't tried the compact (I've just heard this from a lot of people), but I thought this could help.

This has a lot to do with style and preference, but the current king of hoppers is the generally considered to be the Dye Rotor. It has some close competitors though, so my suggestion would be to watch hopper "drop tests" on youtube and see what you think. If the Rotor is out of your price range at $150 you might want to look at a used Reloader B or even the FASTA 18V loader. The FASTA looks a little weird but shoots fast and is fairly reliable.
