I saw in another thread that on the GS400 in wide mode you can 60i recording, but can this be done on the GS150 as well?

Miguel, 60i is the only option on a GS150. 60i just means standard NTSC output of 59.97 fields per second. Two fields combine to create one frame. So on the GS150 both 16:9 or 4:3 are 60i. The GS400 has the option to shoot in frame mode (still technically 60i but the two fields are captured at the same time) or 60i in both 4:3 and 16:9.
