There are enough parts in the pipeline to fix these "OLD" amiga's for 20 more years at least. Not to mention any decent amiga user has spare parts on hand.
This is a silly myth perpetuated by people who are scared of hardware,can't read or are just plain scared of tools i suspect

I've rebuilt about 20 machines and put them back into the world in the last 2 years myself.
Many of the problems are trivial.Some are truly dead and become parts boards.
i would say the only really hard to find part is DMAC4,and most machines run fine on Dmac2
Hi,
I use Cloanto's Amiga Forever 2011. Even though I have all my classics set up, I turn them on about once a week in order to keep the batteries charged. Other than that I use a replaceable PC to use as my Amiga.
Just remember (FRANKO) when that old silicon goes, your pal (not video) is gone. I have one dead A500 and one dead A4000 up in the attic. My original A4000 keeps on singing though. The two dead ones I bought from ebay.
