Yeah, some people ask questions, but they tell us the budget is $200 then the thread just dies lol;
To be very honest; I don't think here's any "good enough" pdw/smg out on the market that is the best "bang for buck" - also that nothing can compete with a M4 CQB Style;- You should re-consider, as there are tons of parts available for m4 series; (and gear) + VFC is well built internally and externally; can't beat the price. .. also don't want you to regret dropping a ton of cash into a MP5 or P90 that will have some issue and then you need to pay out the ass to get it fixed ..
EX:
VFC VR16 Stinger, other variants, $380-440
Here's a fat version of pesto holding one
I mean, if you really are a SMG hardcore fan, then i'd recommend skipping the MP5/P90's; and just investing an the scorpion EVO.. but the gun is 600 new, and 3 set box mag is like $100 on top?
