Mine was $3000 incl 4 welded rod holders. extra ones were $100 each, 10 years ago. So you need $2000 just for the rodholders!
Just a note... when you get one built, make sure you can open the windshield all the way without hitting a brace.
Take a look at mine. It's pretty solidly built and it still got cracks after 10 years. Just had brace plates added last year. There are a couple threads here and you can look at my Albums here.
