That's quite a list you've accumulated. You can narrow it down by picking a style of marker you're comfortable with and then choosing brands you know and can trust. Once you've accumulated a few brands you're comfortable with, take a look at the options each marker model has and make a final choice based on cost versus benefit.
In terms of style of marker, decide if you like Tippmann's approach with longer guns, or a stacked-tube style like Kingman or PMI. Those are the two marker styles you'll most likely find in the $200 range.
In terms of brands of guns, you'll probably want to choose one that is supported in your area. Personally, I believe PMI is producing a quality product and has one of the best customer service departments in the industry, but I live in the U.S. PMI may not have much support where you are.
If you do decide to go with PMI, be sure to purchase something from the G3 series. The G3 series incorporate a number of upgrades and typically cost less money. For $200 you can pick up a Piranha G3 Pro EXT and for $220 a Piranha G3 Pro TS at
www.paintballgear.com Both are VERY nice markers for the money, coming with vertical feeds, drop forwards, regulators, and quality bolts. They shoot consistently, break very little paint, and field strip in about 5 seconds.
Good luck with your decision.
