For what you want I would say the Singer 15-91. Sews super fast too. It is consider the no. 1 vintage singer for doing actually quilting. I just got mine set up for that.
The singer 301 is lighter and would be nice as a full size portable machine. It is considered the big sister of the feather Weight eventhough it looks none like it. there is a cute little handle on top to cary it. Still not a super light machine though. also it is does not sew through as much as the 15-91. I like this machine for paper piecing but not for quilting.
Singer 301 Note the cute cary handle. It comes in tan, black or two tone white and tan.
