I got bored waiting for a decent accelerator & SCSI controller and sold my A1500 a couple of months ago. I only wanted to get it to A2500/30 spec anyway, although I would have been tempted. I think there is a limit to the number of people who want a fast processor in an ECS machine.
I'm in the same boat.
I'm not spending over $500 for an upgrade for a machine I got for less then $100.
An '030 would suit me fine, too.
After all we're talking slow ('060), really slow ('030), and damned slow (stock).
If I want fast I'll use UAE or MorphOS.
