Sway Bar Help

i am currently restoring my 72 duster, and while its still on the rotisery i would like to add a front swaybar, but at the same time i would rather put the 200$ somewhere else, plus i do not have sway bar lower contol arms, so i will have to do some work to them. My question is to those of you who have a car that you drove without a swaybar and then decided to put one on, what was the difference handeling wise? was it really worth the 200 bucks or did it not help it too signifigantly. please let me know your thoughts, if you could send me a pm that would be great, thanks
