I would advise you to get a Tippmann. Spyders are actually pretty decent guns (despite what the naysayers suggest). but you WILL break something on your Spyder long before anything ever goes wrong with your Tippmann. The reliability of Tippmann is legendary, and don't worry about a little extra time to take the gun apart. Basically, you won't be needing to because these things are work horses.
Here is a little anecdote: When my friends and I decided to get into paintball several months ago, the 4 of them went with Spyder Pilots and I bought a Tippmann Custom Pro. Best decision ever. By the end of 8 hours of play, 3 of the 4 Pilots had something broken or malfunctioning, and every one of them had been taken apart multiple times to clean chops. I never had to do anything except load more paint into my hopper. Oh, and wait around for everyone else to finish cleaning their chops. I painted alot of trees around that campfire.
As far as accuracy goes, many consider this blaspehmy, but accuracy comes mostly from a good paintball to barrel match, and not so much from an overpriced barrel. You can get great accurracy from almost ANY barrel. If you put the paintball in your barrel and it rolls out, you will experience horrible accuracy. If it gets stuck and won't come out, you will break balls. The optimum length is about 12-14 inches. ANything shorter and your ball won't get up to speed, anything longer and you just mess up your accuracy.

Check out that site for barrell and air system info, it is very helpful.
Also, Tippmanns work just fine in 'speedball'. You won't be shooting 15bps, but if that is your goal you wouldn't want a SPyder OR a Tippmann. I took out a Shocker and a Matrix with my lowly Tippmann CP. It all comes down to how you use what you have.
