It may be a fine kit, but it doesn't hold a candle to DJ Base's kits. Here to Canada, it was actually less to order them in from Germany then the US.
Below are the pictures from my A2000, A3000, and A4000. you can see how good it looks.
Nicely done. I just did my 2000 tonight after pulling it from the shelf for its first annual inspection since 2006.
I replaced R803 with an 1N914/1N4148 switching diode (RadioShack #276-1122.) As mentioned elsewhere, this prevents the charging circuit from attempting to charge the replacement battery. The replacement battery is a CR-2032 in the appropriate spring-loaded holder with three pins. Unfortunately, the spacing of the positive pins do not match the old NiCD. A CR-2016 holder might.
The battery shows 3.44V, while the cathode side of the diode shows 3.03V, for a voltage drop of .41V. Less than a silicon diode, but more than what I would like.
The attached pictures are the results of my handy work. First is the solder side of R803 and the battery holder. Second is the component side of both. Lastly, the back of the battery holder showing the mismatched spacing of the positive pins.
