oh boy.well i can assure you,any one of these are going to wake you up to whats on the market now.they will totally blow the panny 3500 out of the watter.
good basic runners with great support:
sv4k
vs ultra
cnx mini
cw 700
captain 7100
i like captain 7100.she's the one with the most juice.
(twice the ram as the others)
superior pic quality as well.and surprisingly,one of the lower cost's.she also can run iks if you wanted with adapter sold separately.don't have to though,her file support has been mean enough lately.some really nice hardware and software both.captains gaining popularity,and its great to see.
i would rank it as literally 5 times (at least) the unit the 3500 is.iv no doubt in my mind,you would also if you decide to give her a spin.
have a look and see if you think she would be a nice step for ya buddy:
