I've been brewing for over 20 years and have accumulated $$ in upgrades over the years. I don't brew as much anymore thanks to kids' schedules and the wonderful assortment of beer now readily available. Borrowing equipment or supplying the kit is a great way to see if you like it.
Couple things -- sanitation is key and quality ingredients are going to make better beer.
Send me a PM if you have any specific questions.
And the Great American Beer Festival is worth the trip, just saying.
