LIke Got Uzi mentioned.. some of those things are heavy and a pain to setup. The two you chose I would say are a pain. Fun but nevertheless a pain to move.
I use subguns way more than belt feds but I see you don't want a subgun.
Possibly a 1919? I think that is in that price range but I could be wrong with all these price fluctuations.
Or possibly a F/A AR-15 variant might give you some options.. From shooting different uppers.. which includes things like the Razorback in 22LR and MCR belt fed.. though I prefer to shoot subs.. Cheaper, controllable and fun.
What ever you choose, be sure to study up on them and get spare parts.. and most of all enjoy it.
