The factory BNR32 plastic bar is the best option, no doubt - The problem is finding one at the right price. They pop up occasionally on SAU but are usually snapped up very quickly and they can still fetch pretty decent money.
There is a beautiful 1994 white BNR32 thats just been added to the Prestige Motorsport list and it looks like a top example.
Asking price is $21000, and includes full compression test and mechanical check information from Prime Garage.
Worth checking out
Ryan, I have the bar from Just Jap on my R32 - Heres a pic
My painter was impressed with the quality of the bar and its raw finish - Its very sturdy, not like some of the flimsy fibreglass shit I have seen around.

Just bare in mind when it comes to fibreglass bars you usually get what you pay for.
A lot of cheapo bars require a lot of work to get them up to scratch and ready for fitting and painting and quite often the extra expense of doing this adds up to more than it would have cost you to pay that little bit more for a good quality strong bar in the first place
Edit
Box was sold to me for an agreed price and was due to be picked up today, however this seller has now reneged on the deal because he 'got a better offer'.
Not impressed, very poor form.
Sadly, its situations like this where you need your insurer to be there to back you up.
Any time you have an accident, report it to the police as there are too many people out there that will try and screw for all your worth even if you only scratch their car.
The other thing to bare in mind is prices are always changing, if it were me, and I was genuinly wanting to buy the kit from a dealer here, I would ring them to discuss their price and negotiate from there
