Having the bed extension and tailstock and tool stock risers as a kit is best value for buck in their accessories, followed closely by their lights; I have two of their lights. I also have the 24-36, which is a different kettle of fish, the 18-36 feels like a midi lathe by comparison. That said the 18-36 would be my mid lathe choice as its functionality is just great; a real lot of thought has gone into the design.
Another advantage I have used twice, is to place the bed extension in the front sticking directly towards the turner. In this position, one slides the headstock down a bit and with the tool rest placed onto the 90º placed extension, one can turn a full sized bowl rear without having to remove the bowl blank from the chuck or faceplate. The bed extension can be attached in five positions.
The diagonal of that rough blank is approximately 900mm, the lathe is running almost at its limits; so was I.
