Would there be a big difference in reliability for tournaments between the etha and a high end?

[KiboshX]

i don't think so...you get alot of marker for your money with the etha

it wouldn't be a problem- especially if it's reliability that you're questioning.

The Etha would work great in tournament ball. I've used mine twice and so far i dig it.

Differences really if how its built, mechanics and feel. Each marker has its own perk its up to you to buy what you like not what everyone else will suggest. If your worried about will it perform like a highend, then yes it will definately shoot just as fast as any highend.
