Hi! I am the main developer of the 1541 Ultimate. Currently, working hard on compatibility with different revisions of the commodore machine, and adding new features.
The list of pre-orders is growing; yes it is possible to order it now. The price is € 99 for the normal version, and € 119 for the "plus" version (with 32MB ram). :-D Just send me an E-mail with your name, and which version you would like to have.
The list is currently so long, that the delivery time for the units will be around 8 to 10 weeks.
