If you maintain it well the gun will run great. You may blow out an internal seal every now and then if you get it shooting fast on a co2 tank, and the thing will be a terrifyingly loud gas hog, but it'll run fine. Spyders are good starter guns, though I would recommend looking into an M3 Black Dragun, the things are duplicates of spyders, with a decent electro grip for about $150 (american). Its about what you'd pay for a Shutter, and as far as I'm concerned its a better gun, it lets you play recball just as well and if you start drifting towards tourneys it will let you compete at that level as well.
Edit:
I guess I should tell you that I own an Dragun myself, I use it as a backup now and for a season it was my main gun. A friend of mine bought a shutter, then put on an electro grip (I believe it was called a "Sprint" though I'm not sure). In the end, he payed about a hundred more for his setup, which wasn't really worth it. The shutter is a larger, heavier marker so it'll be a little unweildy, but he did have a full auto feature (boy did we have some fun with that
).
