I mean this next part in a sincere and non-defaming way...
Don't go cheap.
There are deals - and then there are "cheap alternatives". If you go cheap - you aren't likely to be satisfied with the quality of workmanship of the product you're playing with. I can't begin to tell you how many times I made this mistake before wising up and learning that you can't financially short-cut your way into a good and fun day out.
Best example of these are hoppers and masks -
While you can get an inexpensive mask for $30 that is rated to save your face from 300fps impacts, it won't be dual pane. The foam probably won't be as comfortable as it could - and its likely a single, unhinged piece. I've been there. I've looked at the $110 mask at the top of the line, and made the $30 decision so I could still afford a case of paint that paycheck. Upon using the mask- I found out why it was $30. That's not to say that you can't get good stuff for less... but going for product based on price...more so than learning the price points? You won't be a satisfied customer.
If you want a grav-fed hopper..it'll run you 4 bucks. The next step up is a Proto Primo - for about $20ish. From there - they make a variety of garbage agitation hoppers...that should be skipped. The Fasta comes in between 65 and 75. The Halo Too between 65 and 85. Pinokio around 100. Then the Rotor/Prophecy/Spire at the price for most entry level markers.
Masks are between 65 and 120. Make sure they're dual pane.
Tanks - American made tanks are going to have fresher hydro dates, and easier servicing and warranties. Ninja is a great company to work with - though they're on teh ASTM board and won't re-install older regs that... while still good..don't meet the required ASTM thread length. Crossfire has poor customer interaction, but provides a quality product at a price that...I guess...compared to the industry - warrants the level of customer service. I forget the 3rd...CP? Expect to spend about $150 on a new, recently born xx/4500psi tank.
What you have is usable and probably will suit you alright with what you have...but before you throw more money at a marker that really...won't get any better...upgrade around the marker. If you can't justify the expense - have fun with what you have
