If you're wanting to get into speedball, you're going to need an electronic gun. In that price range, the Mini is going to be tough to beat. It's the same basic engine as the Axe, and you get Empire's customer service, which tends to repair or replace broken stuff for free, no questions.
By the way, going to move this over to the VS section. You're likely to get a lot of suggestions.
For the record, accuracy is only affected by the cleanliness of your gear and the quality of your paint. An enmey will be just as accurate as a luxe in the same conditions.
And like Scout said, if you want to enter tournaments you'll want an electronic marker. You likely won't be competitive with a mech gun due to the rate of fire, or you'll at least be at a disadvantage. If you guys like the enmey then you might look into the extcy. I know it can be found used for around that price, and should be tournament ready. Hope this helps!
if you like the enmey you can look at the vibe/ion/extacy all of them are practically the same. i would look into the mini and since the price is lower a shocker. the Axe isn't out of the question if you can find someone wanting to do a quick sale you can get them for less than 200. how soon do you need it and does he already have a nice mask tank and hopper?
