Accelerator for Amiga 600 advice

[Iggy]

I want to buy an accelerator for my Amiga 600.
 
The ACA 630 looks perfect but that is not available anymore.
 
The ACA 620 looks to considerably less powerful ? Especially as its only got a 68020EC with approx 10MB instead of the full 68020 with more memory.
 
I see there is also something called a Furia S628. Do you need to order this direct from the creator ?
 
Anyone know which is quick ACA 620 or Furia S628 ?
 
Anyone know if any more ACA 630's are ever likely to be produced again ?

The reason for the shift in production is the availability of processors.
And no, the ACA630 is probably out of production.
Look for a used one.

If you are only going to produce a few, virtually any 68K processor is still available (except some of the late mask '040s and '060s).
 
But finding a good source for any quantity can be difficult.
These are old chips.
