From my experince you are probably not going to need bipods too much so you could save some money for upgrades there.

I personally really like the aps system. Especially the feeding system on it is so idiotproof that you will never have to worry about doublefeed's. On the other hand upgradin a VSR will be alot more cheaper when aps will basically need all new internals in higher fps. Since you're low on money, I would probably go with vsr(or vsr compatible).
