We have a booster seat that lives in the car ready for if we go out to a restaurant or a friends place. It's the best thing we've bought really.

But I don't know that I'd use it as a permanent high chair. I like our highchair, and it feels safer than the booster seat.. has the 5 point harness in it, and I'm able to leave DS to eat in that while I do other things. He doesn't seem so secure in the booster seat.

I do like that he sits at the actual table with us tho with the booster seat. So I dunno.. hehe. Perhaps start with the booster seat (it's much cheaper, and soooo handy to have anyway) and if you don't like it as a permanent, then get a normal highchair.
