To give you a couple of examples of my thinking on this, Mr Bojangles: Hales speakers, Counterpoint gear, EAD gear, Cello, Theta and there are others that I cannot think of right now.
Idler Garrards were for many years not valued highly at all ...I think only recently have they come back. Top end Micros the same thing.
Oh yes, DaveyF
The thing is, prices are not likely to go up immediately after makers of iconic equipment cease to trade. Up and up escalation of market prices will depend on rarity, quality and demand.
Following the last number of posts in this thread, I'm happy to read all of this seems to have been a false alarm
OT - elsewhere on this board, I may have mentioned I have altogether 5 Garrard 301's. Long ago when I started buying them, this was not by design or 'grand plan' to invest in a particular turntable I knew beforehand was going to fetch silly prices in a decade or two. These acquisitions 'just happened' as I was in the right place at the right time.
The first (in the avatar) was acquired for the equivalent of US$1. It was due out with the trash on the day I acquired it and stayed unused stored on a rack in my workshop for a few years before I had a closer look and saw its potential.
The next two was offered by someone I knew for the equivalent of US$10 apiece around the mid 80's.
Number 4 was purchased at a local flea market for US$2 and was my first grease bearing model and number 5 - another grease bearing version - was a 'present' from a customer I had assisted with servicing his 301 and the setting up of a new cartridge.
He hadn't played records for years and wanted to rip some vinyl for his son living in UK.
Months afterwards, the old gent called me and offered me the 301 (fitted with an RKG - something Ortofon 12" arm), and all of his records.
So airbearing - keep the faith

, your wish for a low price Aussie deck one day, may well come true.
