It depends on the mods you put on it (if any). If it still has all stock parts (no mods) then a 5 dollar hopper is fine as long as it's sturdy. If you put a anything on it to increase the bps (fire rate) such as an e-trigger or a WAS board, then you may want to find a good battery operated cyclone feed hopper.
This statement is half true but half untrue. The tippmann A5 and 98 custom do indeed have different threads. But after the A5 tippmann made the X7 which has identical threads to that of an A5. Because of this a barrel with "Tippmann A5" threads, will fit on a tippmann x7, but will not fit on a tippmann 98 custom.
The best type of paintball for the 98 series is a mid grade paint (anything around 60 dollars like Diablo All Star). As for any gun, you don't want to just buy the cheapest paint possible (monster balls) because of the poor consistency and tendency to bounce after impact, but too high quality paint (easily breakable) in a Tippmann will chop a lot of paint.
what i think the best type of paintball gun for a new comer would be the tippmann 98 custom its a cheap reliable gun that can take almost any abuse you put it through acurate and fair weight its for of a senario type of gun if your looking to shoot like 20bps youll be dissapionted but if your looking for an all around good gun that you can rely on the tippmann 98 custom is a great gun ive owned myn for 2 1/2 years and its still kicking like its brand new no break downs or repairs also a big advatege of this gun is its very customizable i have a 98c with a folding stock and a 14" barrel and an electric hopper and it comes with a sight so for a new guy that's a bonus in concluson could rave about this gun forever how its one of the most selling guns in the world but once you have played for a while you might want to upgrade to an tippmann a-5 or x7 thanks jamie-shivers
Pigments are the best type of colorant for mixing custom paint colors.
The Project Salvo has Tippman 98 Custom barrel Threads.. Same with the Alpha black
The best upgrade would be the cyclone feeder. You can also purchase a Flatline Barrel but they can be tricky and require that you buy better paint. Trigger or firing mode mods are often not the best upgrade due to the semi-auto only requirement of most parks.
hopper hopper
The best kind is Mits at Custom Mobility.
A small one that fits.
There is a wide variety of starter guns. The Tippmann 98 Custom is probably the most durable, but if your are looking for a faster, more speedball type gun, I would highly recommend the piranha EVO. It's running at about $200 or less.
I guess hopper has grass.
Custom is best but boil and bite will do the trick.
