Maybe you've seen this on Atari-Age or at ABBUC, there's a nice update for a 1050 drive.
It can emulate 10 different drive enhancements, like Speedy, Happy, US-Doubler and Archiver to just name a few.
More details can be found at: http://www.horus.com/~hias/atari/#megaspeedy
or at the site of Steve Carden: http://www.realdos.net
Orders can be placed at: firstname.lastname@example.org
Price, 50 Euro for the unit, 5 Euro extra if you're not an ABBUC member.
Shipment in / to Germany is 4,50 and the rest of the world for 6 Euro. (Ask to be sure)
If payed by PayPal, there's an extra charge of 1,50.
Right now, we have a policy of 1 unit per buyer. But a 2nd batch will be run, so you may also notify your intrest in more units.
