If you don't want to wait, you can order an NTSC 1200 from Vesalia in Germany,
http://www.vesalia.com/. NTSC versions appear from time-to-time on ebay and go from $100-$300. I belive the Vesalia units are made from old parts.
I ordered two A1200s last week from Vesalia - one as a backup and one for my kids. The base price was about $200 with 20GB HD, 3.1 ROMS, and OS 3.5, shipping was another $100 for two units. This did not include the power supply (I use A500 PSUs, they are easy to find on e-bay). Also, these are ESCOM A1200's which have some minor floppy compatibility problems which is not much of an issue today since alot of software has been modified to use the HD.
I've heard mixed opinions about Vesalia, but they were very responsive to my questions before I ordered and I'm hoping I'll have no problems with shipping.
Anyway, good luck!
