Haro did release a few different retro bikes. I have a 2009 Retro Master that I was lucky enough to win!! (I still can't believe it) My son, Toby rides it now. We went for a big ride this morning on it actually.
The 2006 Sport seems to be the best and most sought after of all the retros.
Theres plenty of them in Australia but the best would be in USA mostly. Keep your eyes peeled on Ebay and shoot some questions here if your unsure.
The new Tuffs these days look identical to the mid 80's models but they have sealed bearings and are sweet! I have 3 sets and I love them.
The Chinese parts (Taiwan mostly) are ok for stuff like headsets and small parts.
Checkout Porkchopz as he has gone to a lot of trouble to have parts remade by the OG manufacturers from BITD.
Justin is a great guy too.
