The Indivision also provides HighGfx (1024x768) and supposedly is more consistent (works better, with more different types of monitors) than Amber alone.
And +1 to all the comments about hoarders, you guys in Europe have it easy, where I'm at you're lucky to find one Amiga for sale per year! 
You want an Amiga for sale? A2000 Basic with HDD (refurbed with Coin battery, A2091 with AMD SCSI 2MB RAM, 7.0 ROM's and 1GB HDD)? An A2500HD loaded with a Toaster, TBC IV, 68040 @28MHz + 32 MB 32-bit RAM, aGVP Impact II with 4MB and GuruRom, SCSI Card reader, Thylacine USB, A2065 Network card with HP AUI + Wireless Ethernet bridge, Retina 4MB RTG, Indivision ECS, and CDROM? Or an A3000 68030 @ 25MHz, 2/16MB RAM, 128MB Zoram, ISDN Surfer with Subway USB, GVP EGS Sectrum 4MB, Buster 11, AMD SCSI, and 36GB HDD? Or an A4000T so loaded that I don't have the time to list it?
Then "ring-me-up," Dude.
