Welcome to the forum!
The 80 dollar kit is a good start. You really don't need a secondary for many beers, though you may for a fruit beer as brewers usually put fruit in after the fermentation has finished and they usually do this in a secondary. I would recommedn the Oregon Puree for your first venture into fruit beers. Depending on the fruit 1-2 lbs of fruit per gallon of beer.
As far as if you should use a premade kit or not, there are several very good kits out there. Also a lot of bad ones. Its hard to say exactly, but I have seen the recipes for the www.morebeer.com
kits and the www.northernbrewer.com
kits and they are well designed reciped for the most part.
Also, I recommend picking up a good homebrewing book as soon as you can - check out John Palmer's "How to Brew
" - the website version is free but the actual book is on its third edition and worth the purchase price.
