There are many options for markers. So to each his own.
I use the TIPX. But thats what works for me.
I would suggest taking a real hard look at your requirements of gear and what your game plan is for play. What works for me might not work for you.
I play on a tiny tactical type field. So this is my set up
I always suggest a straight line remote over the coil. It was one of those "Gaaahhh, why did I wait 2 years to try a straight line over a coil" type things. I like the push to connect. But slide check with also work. Make sure to get one or the other.
The TMC is a tippmann 98 in a new shell basically. Which can run COČ I believe. Now, this depends on your climate. But I would try it with COČ first for a while. And maybe try and borrow a HPA tank before you buy one to see if its better. I bought a 68/3000 steel tank because it was cheap. Then I was given a couple 68/3000s fiberglass. And then a 68/4500 Carbon fiber tank. And I ended up going back to a 12oz COČ. I live in central cali. So its normally warmer and I dont have to worry about the liquid COČ being an issue. On HPA the TIPX was only in the 230 range. On CoČ I'm at 259 ± 2 (Limit is 260). Do you want to be light weight and mobile? Or will a big tank on your back flopping about be Ok? I cant stand floppy anything. Its why I don't use a dump pouch or leg holster either. I am a stupidly aggressive player though. With the running and sprints and jumping and hurtling and what not.
So what I mean is how are you gonna play? Your going magfed. So limited paint. How limited? 4-6 mags or 11-15 type player? Your tank will depend on how many mags you have really. No sense on going on to the field with 500-1000 rounds worth of air if you only have 120 on your person. The amount of air you carry should only slightly exceed the amount of rounds you can shoot. My 12 oz COČ will actually last a couple of days for me.
The vest I have been using,
And I just changed it to a similar but lighter weight one. (My Xmass gift from family).
The absolute most important piece of gear is a mask.
Get a GOOD COMFORTABLE mask. Seriously, If getting a good mask means you can only afford 2 mags instead of 5. GET THE GOOD MASK!
Unless you have some experience already. There isnt really a good way to put it in an analogy. A good mask with make or break your day.
The whole budget thing, just requires Patience. If you know what you are looking for. Shop around for the best deal. Go though online sales and clearance sections. Don't be afraid of buying used. Except for clothes.. I...I just cant buy a used mask or like pants/shirts. I have never washed my mask foam...And I know how sweaty I get..
