I'm using Garageband to produce every jingle on W26 (90% of them cause we're also using pre-produced jingles).
I do some VO time to time, it's not the best software you can have, but I'm using it for 3-4 years now and I know it perfectly and I can say it's enough for my needs.
For a start I guess it's a good choice, see after a while if you want to pay for another software. Like I said, after few years, it's still an awesome software for me.
